Hi,
string s = "aXXa";
Console.WriteLi ne(s.LastIndexO f("XX",0));
Console.WriteLi ne(s.LastIndexO f("XX"));
Console.WriteLi ne(s.IndexOf("X X",0));
Console.WriteLi ne(s.IndexOf("X X"));
Result:
-1 (LastIndexOf must also return 1, but gives -1) Is it a bug ?
1 - ok
1 - ok
1 - ok
In documentation it says:
Reports the index position of the last occurrence of a specified String
within this instance. The search starts at a specified character position. 2 3541
No it's not a bug: The LastIndexOf() search works backwards from the
position specified. Hence there is no match for XX from 0.

Yes I see now.

In test() method:
var path="C:\test\hello.txt"; //returns -1 for path.lastIndexOf("\\").
why??
var pos=path.lastIndexOf("\\"); //return -1
But in showFile() method:
We are able to get the filename. The only difference is test()
hardcode the path,
but in showFile() we gets the path from the file dialog.

I am trying to read a line from a text file and store it in a DateTime
veritable. Below is a cut down version of my problem code (in my
actual version I am using a try and catch, and I am receiving each
line in a loop to store into the Array)
If I write the string directly into the array it works, but when I use
the line from the file it doesn't go into the DateTime veriable and I
get an error. Is there something I am missing?

Hi,
I need to be able to split large string variables into an array of
lines, each line can be no longer than 70 chars.
The string variables are text, so I would additionally like the lines
to end at the end of a word, if you catch my drift.
For example, I have a large string variable containing the text:

I realize it's Friday and I'm probably already on vacation for the

there a bug in the .NET 2.0 Framework in regards to the LastIndexOf()
method or am I just not understanding something that should be obvious?
string myString = "This is a test";
int index = myString.LastIndexOf(' ', 0, 6);
The second line throws an ArgumentOutOfRangeException exception, which

Hi Group!
I encounter a strange behaviour of String.LastIndexOf when specifying
start and count values.
The following works:
string tempString = orgString.SubString(0, mycount);
int index = tempString.LastIndexOf(mychar);

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
