public int IndexOfSubString(string[] values, string value)
{
 for (int index = 0; index < values.Length; index++)
   if (values[index].IndexOf(value) > -1)
     return index;
 return -1;
}

See Array.IndexOf.

Thanks for the help,
rod.

Here's something straightforward:

  static int FindStringContainingText(string[] strings, string textToFind)
  {
     for(int i = 0; i < strings.Length; i++)
     {
        if(strings[i].Contains(textToFind))
        {
           return i;
        }
     }
     return -1;
  }

Returns the index of the string containing the text you're looking for, or -1
if not found.

call e.g. like so:

 int foundPosition = FindStringContainingText(theArray, "42");

With C# 3.0, you could also use LINQ:

 foundPosition = Enumerable.Range(0, theArray.Length).First(i =>
theArray[i].Contains("42"));
