如题，如何分别获取
string str=
"IO1=001
 IO2=运行
 IO3=停止
 IO4=X10"
中=后的字符，即001，运行，停止以及X10
备注：=后的字符串是可变的
谢谢！

没有人吗

你等于后的字符长度没有规律啊！

Arraylist lst=new Arraylist();
for(int i=0;i<str.Length;i++)
{
   if(s[i]=='=')
   {
      for(int j=i+1;j<str.Length;j++)
      {
        if(str[j]=='=')
        {
            string s=str.SubString(i+1,j-i-3);  //可能个数有点问题，楼主酌情加减1
            lst.Add(s);
            break;
        }
      }
   }
}

先按'='进行字符串切分，从切分结果中取出'I'之前的部分

程序代码：
string str = "IO1=001 IO2=运行 IO3=停止 IO4=X10";
            int i = 0;
            ArrayList resList = new ArrayList();

            while(i < str.LastIndexOf("="))
            {
                int j = str.IndexOf("=", i + 1);
                int m = str.IndexOf(" ", j);
                if (m < 0)
                    resList.Add(str.Substring(j + 1, str.Length - j - 1));
                else
                    resList.Add(str.Substring(j + 1, m - j));
                i = j;
            }

已解决 3楼5楼没有理解我得意思 不过还是感谢
我说的是从一个文档里面读取数据 =后的字符没有规律
        static Label[] InputLable=new Label[16];
        static string[] StrSub=new string[34];
        static string[] StrLable = new string[32];

           InputLable[0] = label0; InputLable[1] = label1; InputLable[2] = label2; InputLable[3] = label3;
            InputLable[4] = label4; InputLable[5] = label5; InputLable[6] = label6; InputLable[7] = label7;
            InputLable[8] = label8; InputLable[9] = label9; InputLable[10] = label10; InputLable[11] = label11;
            InputLable[12] = label12; InputLable[13] = label13; InputLable[14] = label14; InputLable[15] = label15;


                StreamReader InputParaReader;
                InputParaReader = new StreamReader(@"C:\IOName.ini",Encoding.GetEncoding(936));
                StrSub[0] = InputParaReader.ReadToEnd();
                for (int i = 1; i < 34; i++)
                {
                    StrSub[i] = StrSub[i - 1].Substring(StrSub[i - 1].IndexOf("\n") + 1, StrSub[i - 1].Length - StrSub[i - 1].IndexOf("\n") - 1);
                }
                for (int a = 1; a < 17; a++)
                {
                    StrLable[a - 1] = StrSub[a].Substring(StrSub[a].IndexOf("=") + 1, StrSub[a].Length - StrSub[a + 1].Length - StrSub[a].IndexOf("=") - 1);

                }
                for (int i = 0; i < 16; i++)
                {
                    InputLable[i].Text = StrLable[i].ToString();
                }
