The following example creates a System.Text.StringBuilder object to that is used to create a new System.IO.StringWriter. The StringWriter is passed to the WriteXmlSchema method, and the resulting string is printed to the console window.

private void WriteSchemaWithStringWriter(DataSet thisDataSet)
    // Create a new StringBuilder object.
    System.Text.StringBuilder builder = new System.Text.StringBuilder();

    // Create the StringWriter object with the StringBuilder object.
    System.IO.StringWriter writer = new System.IO.StringWriter(builder);

    // Write the schema into the StringWriter.

    // Print the string to the console window.
