Read INIFile from String or Stream

P: n/a
Hi

Is there any way to Read an INIFile from a string or Stream instead of a
physical file ???

I want to read the INIFile into a string then store in a db but when I read
the string from the db or save string to the db I don't want to have to copy
the string to a file to use the WritePrivateProfileString and
GetPrivateProfileString. Is there a way around this instead of writing my own
class to operate on a string or stream ???

Thanks

Hi

Maybe you can use this:

System.IO.StreamReader local_StreamReader = new
System.IO.StreamReader("FilePath");
string local_text = local_StreamReader.ReadToEnd();

Dear Sippyucoonn,

As I understand, you store the content of the .ini file as a string in the
database, you want to read a specified key value from the string directly
afterwards.
If I misunderstand you, please feel free to let me know.

As far as I know there's no directly way to retrieve the key value from a
string or stream, we have to do some string operation, and it's complex to
perform the string operations if the content of the .ini file is very
large. I think you want to avoid this.

However, we have alternative ways to do this:

1. Store the data from the .ini file to a database in a more structural
way.

For example, we can:

1). Create a table with three fields: Section, Key and Value;
2). Call the GetPrivateProfileString API to read all the section,
key and value information into this table;
3). Query the table for the setting information.

2. Use an XML file instead of .ini file to store the settings.

It's more convenience to retrieve a certain value from XML structures
than plain strings.

For exmple, we have the following content in an .ini file:

[Section1]
key1=value1
key2=value2

[Section2]
key3=value3

We can create an XML file to store the content instead in the following
format:

<Sections>
<Section name="Section1">
<key name="key1" value="value1"/>
<key name="key2" value="value2"/>
</Section>
<Secion name="Section2">
<key name="key3" value="value3"/>
</Section>
</Sections>

Then we can store the whole content of the XML file as a single string
into the database.

Afterwards, we can take the following steps to retrieve a specify
setting entry.

1). Read the setting string from the database using SqlDataReader;
2). Create an XmlDocument object;
3). Load the setting information into the XmlDocument object by calling
the LoadXml() method;
4). Call the XmlDocument.SelectSingleNode() method to get the entry we
need;
5). Read the value of the "value" attribute to get the value for the
specify key.

The following sample demonstrates how to do this:

private void button1_Click(object sender, EventArgs e)
{
//read the xml string from the database
//I just assign a specified value for example
string settings = "<Sections>" +
"<Section name=\"Section1\">" +
"<key name=\"key1\" value=\"value1\"/>" +
"<key name=\"key2\" value=\"value2\"/>" +
"</Section>" +
"<Section name=\"Section2\">" +
"<key name=\"key3\" value=\"value3\"/>" +
"</Section>" +
"</Sections>";

XmlDocument settingsXml = new XmlDocument();
settingsXml.LoadXml(settings);

string section = "Section1";
string key = "key2";

string xpath = string.Format(
"/Sections/Section[@name=\"{0}\"]/key[@name=\"{1}\"]",
section, key);
string Value = settingsXml.SelectSingleNode(
xpath).Attributes["value"].Value;

MessageBox.Show(Value);
}

3. Use the Application Configuration File.

This is the recommended way in .NET for storing configuration
settings.

You can read the following article to get more information about the
Application Configuration.
