I use this code to check if string starts with 34CDB:

string word = "34CDBXXXX";

if (word.StartsWith("34CDB")) 
{
   // do something 
}

I want many values, not just 34CDB. I try to change it to

if (word.StartsWith("34CDB", "AT4X3", "3AXP3"))

But doesn't work.

    Question is extremely unclear. What is `stringArray` and how you are going to use it? What have you tried? How do you know that **nothing works**? Errors? – Sergey Berezovskiy May 12 '14 at 11:26

    You tried lots of code, but nothing works. Could you post some of that code? – scheien May 12 '14 at 11:26
  • @user2651946 `columnChars` is an array of `char`. Is `34CDB` valid value for `char`? – Sergey Berezovskiy May 12 '14 at 11:30

    `new char[] { '34CDB', 'E808' }` won't compile and `E808` are 4 characters, not 5. Please show some valid and invalid input/output pairs. – CodeCaster May 12 '14 at 11:30
  • `if (txtBox.Text.Length >= 5){var txt = txtBox.Text.Substring(0, 5); }` and then match against the per-defined values!!! – huMpty duMpty May 12 '14 at 11:32

    Your code won't even compile, make it an array of `string`. Then add following method: `public bool StartsWithColumn(string toCheck, string[] columnChars) { return columnChars.Any(x => toCheck.StartsWith(x)); }`. – Abbas May 12 '14 at 11:37

Perhaps you want to check if the user entered one of your strings:

bool enteredAny = stringArray.Contains(textBox1.Text.Trim());
