Use this code-

string message =" MSGTYPE HEADER 220 I220 PRODUCT CODE 61 :20:31013220~"

string result = message .Substring(0, message.IndexOf(":"));


 
Output
result =  MSGTYPE      HEADER 220      I220 PRODUCT CODE   61

Use split:

protected void Page_Load(object sender, EventArgs e)
{
  string message = "MSGTYPE    HEADER 220    I220 PRODUCT CODE   61 :20:31013220~";
  string[] data = message.Split(':');
  string data1 = data[0]; //contains MSGTYPE    HEADER 220    I220 PRODUCT CODE   61 
  string data2 = ":" + data[1] + ":" + data[2]; //contains :20:31013220~";
  Response.Write("<br>" + data1);
  Response.Write("<br>" + data2);
}

use split

class Program
{
    static void Main()
    {
   string s = "MSGTYPE      HEADER 220      I220 PRODUCT CODE   61 :20:31013220~";
   //
   // Split string on :
   // ... This will separate all the words.
   //
   string[] words = s.Split(':');
   foreach (string word in words)
   {
      Console.WriteLine(word);
   }
    }
}

Ok , for getting remaining part use this code-

protected void Button1_Click(object sender, EventArgs e)

{

string message =" MSGTYPE HEADER 220 I220 PRODUCT CODE 61 :20:31013220~"

string result1 = message .Substring(0, message.IndexOf(":"));

string result2 = message .Substring(message.IndexOf(":"), message.Length-message.IndexOf(":")-1);

}

Output

result1 = MSGTYPE HEADER 220 I220 PRODUCT CODE 61

result2 = 20:31013220~

Try this and let me know.
