c# unicode 编码 中文转换 已测试（转）

中文传参时因为编码不同经常凌乱风中，故传前编成unicode码来过度是一个不错的解决方法

/// <summary>

/// <returns></returns>
public static string unicode_0(string str)
{
string outStr = "";
if (!string.IsNullOrEmpty(str))
{
for (int i = 0; i < str.Length; i++)
{
outStr += "/u" + ((int)str[i]).ToString("x");
}
}
return outStr;
}
/// <summary>

/// <returns></returns>
public static string unicode_1(string str)
{
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;
}
}
return outStr;

}

});
return outStr;
