Generalauto+indentation feature Pin

Hello

I am developing a syntax editor .

I need to give auto indentation feature to my editor .
I use C#.And i use richtextbox.

In the key press event ..

I try the following ..

private void richTextBox1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{

// open and close braces indexes
int indexOfOpen;
int indexOfClose;
int lineno;

if (e.KeyValue == 221) // checking for "}" key
{

System.Diagnostics.Trace.WriteLine(this.richTextBox1.GetLineFromCharIndex(this.richTextBox1.SelectionStart).ToString());

// getting line number
lineno = this.richTextBox1.GetLineFromCharIndex(this.richTextBox1.SelectionStart);

while(lineno>0)
{

/*take the previous line from the position of "}" backwards and if it finds "{" charecter .get the
position of "{" charecter and adjust the position of
"}" charecter to the "{" charecter position.
*/


string[] test = this.richTextBox1.Lines;

string previousline = test[lineno-1];

if( previousline.StartsWith("{") )
{
indexOfOpen = previousline.IndexOf("{");

Point pos1 = this.richTextBox1.GetPositionFromCharIndex(indexofopen);

string currentline = test[lineno];

indexOfClose = currentline.IndexOf("}");

Point pos2 = this.richTextBox1.GetPositionFromCharIndex(indexOfClose);

pos2.X = pos1.X;

}

lineno--;
}

}

// check for the enter key
else if(e.KeyValue == 13)
{
string[] contents = richTextBox1.Lines;
int ilen = contents.Length;
string str = contents[ilen-1];
// setting indentation

richTextBox1.SelectionIndent = richTextBox1.SelectionStart;
}

Its somewhere mistake.I am new to C#.

Please can u correct me or give me sample code snippets?

I will be greatly helpful to me.
