分享到:


//可以包括其他字符
public string uncode(string str)
{
string outStr = "";
Regex reg = new Regex(@"(?i)//u([0-9a-f]{4})");
outStr = reg.Replace(str, delegate(Match m1)
{
return ((char)Convert.ToInt32(m1.Groups[1].Value, 16)).ToString();
});
return outStr;
}

//中文转为UNICODE字符

string str = "中文";
string outStr = "";
if (!string.IsNullOrEmpty(str))
{
for (int i = 0; i < str.Length; i++)
{
//将中文字符转为10进制整数,然后转为16进制unicode字符
outStr += "//u" + ((int)str[i]).ToString("x");
}
}

//UNICODE字符转为中文

string str = "//u4e2d//u6587";
string outStr = "";
if (!string.IsNullOrEmpty(str))
{
string[] strlist = str.Replace("//","").Split('u');
try
{
for (int i = 1; i < strlist.Length; i++)
{
//将unicode字符转为10进制整数,然后转为char中文字符
outStr += (char)int.Parse(strlist[i], System.Globalization.NumberStyles.HexNumber);
}
}
catch (FormatException ex)
{
outStr = ex.Message;
}
}
