字符串取值
我有一个字符串为： <result   value= "1000 "   message= "用户错误 "/>

请问如何分别取到value   和message的值

谢谢！

------解决方案--------------------
IndexOf( "value ")

然后SubString
------解决方案--------------------
use xmlnode or Regex
------解决方案--------------------
try


string yourStr = ..............;
string value = " ";
string message = " ";
Match m = Regex.Match(yourStr, @ " <result\s+value= " "(? <value> [^ " "]*) " "\s+message= " "(? <message> [^ " "]*) " "[^> ]*> ", RegexOptions.IgnoreCase);
if (m.Success)
{
value = m.Groups[ "value "].Value;
message = m.Groups[ "message "].Value;
}

builder.Append( " <contents> ");
builder.Append(content);
builder.Append( " </contents> ");

return builder.ToString();
}
}

楼上3种方法都不错!
------解决方案--------------------
搞点新意。
string str= " <result value=\ "1000\ " message=\ "用户错误\ "/> ";

str=str.Replace( " <result value=\ " ", " ").Replace( "\ " message=\ " ", ", ").Replace( "\ "/> ", " ");
