FileStream Append Data at the top

Question

I am working on a utility.

I want to append data at the top of the file, but it is overwritting not appending.

For eg : Consider the file.txt :

Answer 1

Yes

FileStream fs = new FileStream( path2, FileMode.OpenOrCreate, FileAccess.ReadWrite );

sw = new StreamWriter( fs );

sw.BaseStream.Seek( 0, 0 );

sw.WriteLine( "write new text" );

sw.close()

This method will overwrite any existing data, akin insert and replace.
