            f.Filter = "Doc Files|*.doc|Java Files|*.java|C# Files|*.cs|All Files|*.*"; // and in a similar way you can load any format here.......
            DialogResult dr = f.ShowDialog();
            if (dr == DialogResult.OK)
            {
                s1 = f.FileName;
                richTextBox1.LoadFile(s1);
                open=true;
            }

OpenFileDialog f = new OpenFileDialog(); f.Title = "open file as.."; f.Filter = "Doc Files|*.doc|Java Files|*.java|C# Files|*.cs|All Files|*.*"; // and in a similar way you can load any format here....... DialogResult dr = f.ShowDialog(); if (dr == DialogResult.OK) { s1 = f.FileName; richTextBox1.LoadFile(s1); open=true; }

          using (System.IO.StreamReader sr = new System.IO.StreamReader("TestFile.txt"))
            {
                RichTextBox1.Text =  sr.ReadToEnd();
            }

using (System.IO.StreamReader sr = new System.IO.StreamReader("TestFile.txt")) { RichTextBox1.Text = sr.ReadToEnd(); }

but .doc files will not load as plain text because they are a special format created by Microsoft word. But if you have Microsoft word installed on the computer you are using your C# app on you can load up the Microsoft Word Object Library by adding it into the reference and create an object for reading .doc files.

but the streamreader will read most text formats.
