示例
此代码示例是为构造函数提供的更大示例的一部分 StringWriter() 。This code example is part of a larger example provided for the StringWriter() constructor.
// Use the three overloads of the Write method that are
// overridden by the StringWriter class.
strWriter->Write( "file path characters are: " );
strWriter->Write( Path::InvalidPathChars, 0, Path::InvalidPathChars->Length );
strWriter->Write( Char::Parse( "." ) );
// Use the three overloads of the Write method that are
// overridden by the StringWriter class.
strWriter.Write("file path characters are: ");
strWriter.Write(
Path.InvalidPathChars, 0, Path.InvalidPathChars.Length);
strWriter.Write('.');
' Use the three overloads of the Write method that are
' overridden by the StringWriter class.
strWriter.Write("file path characters are: ")
strWriter.Write( _
Path.InvalidPathChars, 0, Path.InvalidPathChars.Length)
