This sample illustrates how to use multiple encoding formats available from the System.Text namespace. A StreamWriter object is created and passed a Stream object along with an Encoding object from the System.Text namespace. Once created, any output method calls on the StreamWriter object will be written in the specified encoding.

FileStream fs = new FileStream("text.txt", FileMode.OpenOrCreate); ... StreamWriter t = new StreamWriter (fs, Encoding.UTF8); t.Write("This is in UTF8"); Dim Fs As FileStream = New FileStream("text.txt", FileMode.OpenOrCreate) ... Dim T As StreamWriter = New StreamWriter (Fs, Encoding.UTF8) T.Write("This is in UTF8") FileStream* fs = new FileStream("text.txt", FileMode::OpenOrCreate); ... StreamWriter* t = new StreamWriter (fs, Encoding::UTF8); T.Write("This is in UTF8");

A StreamReader object is used to read text in a given encoding and is constructed in the same manner as a StreamWriter object.

FileStream fs = new FileStream("text.txt", FileMode.Open); ... StreamReader t = new StreamReader(fs, Encoding.UTF8); String s = t.ReadLine(); Dim Fs As FileStream = New FileStream("text.txt", FileMode.Open) ... Dim T As StreamReader = New StreamReader(Fs, Encoding.UTF8) Dim S As String = T.ReadLine() FileStream* fs = new FileStream("text.txt", FileMode::OpenOrCreate); ... StreamWriter* t = new StreamWriter (fs, Encoding::UTF8); String* s = t->ReadLine();

The following example illustrates creating StreamWriter objects of different encodings and using each object to write to a text file.
