How to detect the actual length of a string containing Chinese Characters

String mystring = "Ximen Yifan's blog -- 2010 ";

 

Asciiencoding mydata = new asciiencoding ();

Byte [] mybytes = mydata. getbytes (mystring );

// Mylength is the actual length of the string

Int mylength = 0;

For (INT I = 0; I <= mybytes. Length-1; I ++)

{

// Determine whether it is a Chinese character or full-legged symbol

If (mybytes [I] = 63)

{

Mylength ++;

}

Mylength ++;

}

String myinfo = "" + mystring + "" Total "+ mystring. length. tostring () +" characters ,";

Myinfo + = "actual length is" + mylength. tostring () + "bytes. ";

MessageBox. Show (myinfo, "message prompt", messageboxbuttons. OK, messageboxicon. information );
