sscanf in c#

[AMP]

Hello,
Anybody know if anything exists like sscanf in c.
I found a few things OL but most were pretty old. Maybe something has
come along since 2004?
Thanks

| | Well, suppose you have the following string:
| |
| | "Item #1: $32.53 Item #2: $32.54 Sub-Total: $65.07"
| |
| | With sscanf, I believe you can do something like:
| |
| |
| | sscanf(buff, "Item #1: $%d Item #2: $%d Sub-Total: $%d", value1,
value2,
| | value3);
| | printf("Sub-Total: %d", value3);
| |
| |
| | Using regex, you can do something similar...and parsing out yourself
| would
| | be more trickier...

| grr, that's not my point. The OP requested similar functionality to
sscanf.

Sorry, but I'm affraid we'll have to agree to disagree. I don't see how a
simple C library 'function' like sscanf compares to Regex, a 'library' and a
complex engine on it's own, it's too heavy weight compared to sscanf.

I know you can achieve the same using RegEx, but I can do exactly that using
some minimal code arround the individual type's Parse and TryParse methods.
Notice, that the OP asks about sscanf, this means he has a C background,
chances are that he know little/nothing about RegEx, maybe he will prefer to
use Parse and TryParse, the choice will be on him.

I do see where you are coming from. And yes, I will continue to disagree as
we have previously agreed to allow :) On second thought, maybe I will agree
with you about parsing out manually depending on the amount of data the OP
needs to parse. If it is a larger amount of data, and performance isn't an
issue, then I would then go with Regex for this.

sscanf (and family) is often used for very simple parsing in C. Something
like this:

// query registry value.
if( ERROR_SUCCESS == RegQueryValueEx A( hKey, "whateverString ", NULL,
NULL, (LPBYTE)szResul t, &dwResult ) )
{
// parse result
if(sscanf( szResult, "%x", &dwResult ) == 0)
...

is very common, and the equivalent in C# looks something like...

int dwResult ;
string installResult = rk.GetValue("wh ateverString");
bool result = Int32.TryParse( installResult, NumberStyles.He xNumber,
null, out dwResult );
if(result)
// hexVal contains a correct hex value.
...

This illustrates the equivalence of sscanf and Parse (or preferably:
TryParse).
I (nor you!) would never use RegEx for this.
If it is a larger amount of data, and performance isn't an
| issue, then I would then go with Regex for this.

| :)
|
Agreed, but that's not my point.

Hello,
I am the OP.
I am beginning to understand but I have the following:
sscanf(strdata[1], "%lx\n", currentAddr);

currentAddr is an unsigned long in c(which is a uint in c#) 4 bytes,
correct?

I am trying to get the hang of this, but I could use an example with
something I'm using.
I have to convert about 8 of these to dfferent formats, so its
important I can understand what I;m doing.

Thanks
Mike

Also, theres this qualifier (3), which is the max number to read, in
the following that I would have to deal with.
sscanf(strdata[linepos], "%3x", blkout[dataframelen]);

I appreciate EVERONES help with this.

For the following:
sscanf(strdata[linepos], "%3x", blkout[dataframelen]);
What it looks like to me, is we are taking (strdata[linepos],
formatting it and storing it in blkout[dataframelen]. So were not just
checking something, we are moving the values to another Array and
formatting them at the same time.Am I correct?
And no I'm not a c programmer, I'm trying to convert a c program to c#,
so I'm learning c at the same time, so Im looking to do the same exact
thing in c# that has already been implemented in the c version.

And with everyones help I have learned a great deal along the way. I am
about 90% done.
Thanks Mike

| | With sscanf, I believe you can do something like:
| |
| |
| | sscanf(buff, "Item #1: $%d Item #2: $%d Sub-Total: $%d", value1,
value2,
| | value3);
| | printf("Sub-Total: %d", value3);
| |
| |
| | Using regex, you can do something similar...and parsing out yourself
| would
| | be more trickier...

null,

| grr, that's not my point. The OP requested similar functionality to
sscanf.
| The closest he can get is by using Regex...sure, you can parse it
yourself
| into an array and access the individual elements, but that's not what
the
OP
| was originally asking AFAIK (even though, it should work for the OP).
| Anywho :)

Sorry, but I'm affraid we'll have to agree to disagree. I don't see how a
simple C library 'function' like sscanf compares to Regex, a 'library' and
a
complex engine on it's own, it's too heavy weight compared to sscanf.

I know you can achieve the same using RegEx, but I can do exactly that
using
some minimal code arround the individual type's Parse and TryParse
methods.
Notice, that the OP asks about sscanf, this means he has a C background,
chances are that he know little/nothing about RegEx, maybe he will prefer
to
use Parse and TryParse, the choice will be on him.

I do see where you are coming from. And yes, I will continue to disagree as
we have previously agreed to allow :) On second thought, maybe I will agree
with you about parsing out manually depending on the amount of data the OP
needs to parse. If it is a larger amount of data, and performance isn't an
issue, then I would then go with Regex for this.

| Hello,
| I am the OP.
| I am beginning to understand but I have the following:
| sscanf(strdata[1], "%lx\n", currentAddr);
|
| currentAddr is an unsigned long in c(which is a uint in c#) 4 bytes,
| correct?

Yep.

| I am trying to get the hang of this, but I could use an example with
| something I'm using.
as per my previous sample...

uint currentAddr;
string strData = " ff12fffe ";
bool result = UInt32.TryParse (strData.SubStr ing(1), NumberStyles.He xNumber,
null, out currentAddr);
if(result)
// parsed correctly.
else
// failed to parse.

or, you can use the Parse method.

try {
hexVal = UInt32.Parse(in stallResult.Sub string(1),
NumberStyles.He xNumber);
}

string strdata = " ffc2fffe Hello ";

hexVal will contain 000000ffc;

But why don't you read the docs and try yourself?, it takes 5 minutes to
test all your cases, waiting for an answer may take hours.

I have been trying, but there is a problem with the type conversions
also
sscanf(strdata[linepos], "%3x", blkout[dataframelen]);

strdata[linepos] is a char Array
%3x is "Read a Max of 3 Chars and format it as an int."
blkout[dataframelen]); is a byte Array

So to me I see:Read a max of 3 chars from strdata, format it as an int
and store it in blkout[dataframelen](a byte) I dont know how to do
that.

The entire section of code:
/* Transfer data in line into blkout: */
for(linepos= 0;
linepos < linelen-3; linepos+= 3, dataframelen++)
{
sscanf(&strdata[linepos], "%3x", &blkout[dataframelen]);
/* (Max 16 bytes per line!) */
}
Thanks
Mike

Well, consider following sample...here I assume that the input buffer looks
like:
buffer = " ff c2 ff fe de de ba ba cc 12 25 66 9a 63 55 87";

....
byte[] ahexVal = new byte[16];
installResult = " ff c2 ff fe de de ba ba cc 12 25 66 9a 63 55 87";
for(int n = 0, m = 0; n < 48; n+=3, m++)
result = Byte.TryParse(i nstallResult.Su bstring(n, 3),
NumberStyles.He xNumber, null, out ahexVal[m]);
foreach(Byte b in ahexVal)
Console.Write(" {0:x}", b);

So what I'm doing is parsing the buffer, checking for a valid hex number
sequences (every third character starting from 0 with a width of 3
characters)). Every valid hex value will be stored as a byte value in an
array of bytes.
But, I would urge you to start thinking in terms of C# and the framework.
While both C# and C share some common grounds as a language, the C library
and the FCL on the other hand do not, that means that you should not try to
mimic C contructs in C#, it's a waste of time.
Also don't think you can learn both C and C# at the same time, you'll have
to make a choice, and because you are here, your choice should be C#.
Start with C# and spend most of your time with the FCL, it offers a much
richer set of API's than the C library.
