//--------------------------------------------
// in your function
List<string> nameList = GetNameList("UserName: tghgd bhbj bhbh hb");
foreach(string nameItem in nameList)
{
// MessageBox.Show(nameItem);
}

//--------------------------------------------

List<string> GetNameList(string name)
{
List<string> nameList = new List<string>();

string[] words = null;

int valueOf = aLine.IndexOf(":");
if (valueOf < 0) return nameList;

string nameValue = name.Substring(valueOf + 1).Trim();

words = nameValue.Split(' ');

foreach (string wordItem in words)
{
nameList.Add(wordItem);
}
return nameList;
}
//--------------------------------------------

Try

var myStr = "string = UserName: tghgd bhbj bhbh hb";
var cln = myStr.IndexOf(":");
var output = myStr.SubString(0,cln);

That totally doesn't fit through, you left the important points of questions, you need to tell whether it is the first element you want, or the last or the username itself and so on.

But, let me go through a few examples, if it is the first element you want in your string, then the following code would be enough.

C#

string completeStr = "UserName: tghgd bhbj bhbh hb";

// Split and select the first element in the array string[]
// 1. Split would get a character, upon which to split the string 
// 2. We use an indexer to select an element at some index; here it is first element
string firstElement = completeStr.Split(':')[0];

// For trimming..
string trimmedStr = firstElement.Trim();

You can read the MSDN documentations to learn more about these functions, and how are they used in your application. You will find good code examples of these methods there, and some remarks from the developers about these functions.

https://msdn.microsoft.com/en-us/library/system.string.split%28v=vs.110%29.aspx[^] Contains all of the overloaded methods for Split function.
https://msdn.microsoft.com/en-us/library/t97s7bs3%28v=vs.110%29.aspx[^] Trim function.
https://msdn.microsoft.com/en-us/library/2549tw02.aspx[^] Might be helpful to read for indexers.
