If you can't read my code, try converting it here[^]

string inp = File.ReadAllText(@"D:\Temp\MyText.txt");
string match = "FindMe";
int count = Regex.Matches(inp, match, RegexOptions.IgnoreCase).Count;

if (line1.IndexOf(cust1[AddressLength1].ToString(), StringComparison.OrdinalIgnoreCase) != -1)

if (!String.IsNullOrEmpty(CustodianEAddressText))
{
  List<string> list1 = new List<string>();
  using (StreamReader reader = new StreamReader(FileLocation))
  {
    string line1;
    while ((line1 = reader.ReadLine()) != null)
    {
      list1.Add(line1); // Add to list.
    }
  }
  for (AddressLength1 = 0; AddressLength1 < Length; AddressLength1++)
  {
    string cust1AddrLen1 = cust1[AddressLength1].ToString(); // only needs .ToString() if cust1 is not string[] or List<string>
    // If you don't need the LineArray1 populated this 1 line works:
    count1 = list1.Count(l => l.IndexOf(cust1AddrLen1, StringComparison.OrdinalIgnoreCase) != -1);
    // If you DO need LineArray1 to be populated with the matching lines, then these 2 lines work:
    string[] LineArray1 = (from line in list1
                           where line.IndexOf(cust1AddrLen1, StringComparison.OrdinalIgnoreCase) != -1
                           select line).ToArray();
    count1 = LineArray1.Length;

    string count1a = count1.ToString();   // I'm assuming you're using this somewhere you haven't shown... or else it isn't necessary

    using (StreamWriter filed = new StreamWriter(FileLocation, true)) // is this really the SAME FileLocation as above??
    {
      filed.WriteLine();
      filed.WriteLine("The email address {0} was found {1} times within the recipient's inbox", cust1AddrLen1, count1a);
    }
  }
}
else
{
  MessageBox.Show("Please Enter an Email Address");
}
