Let's here consider that your CheckBox.Checked property is false, what happens? You're trying to convert the value of your variable. At the end, you're using it! But how should the compiler know what value it's worth? Here's a link that explains this error in depth: Compiler Error CS0165. You need to tel the compiler that you know what you're doing. How?

Archived Forums V > Visual C# Language Question 0 Sign in to vote Ok I'm not seeing how this is producing an error so I'm sure it's something simple. string[] account; //See if the account number has a - in it if (args[1].Contains("-")) { //trim it up //temporary for now account[0] = args[1].Substring(args[1].IndexOf("-") + 1, args[1].LastIndexOf("-") - args[1].IndexOf("-") - 1); account[1] = args[1].Substring(args[1].LastIndexOf("-") + 1); } else account[0] = args[1]; it's producing the error on account[0] in the if portion of the loop not the else portion.The blue line is only under account. account[1] is fine and so is account[0] in the else portion as well as the rest of it of which I didn't include.

(try to use it as auto expandable dynamic array) if you want to expand the array as it goes on please use ArraList instead of static array please see the the following code where I defined array have 5 elements upfront string[] account =new string[5]; //See if the account number has a - in it if (args[1].Contains("-")) { //trim it up //temporary for now account[0] = args[1].Substring(args[1].IndexOf("-") + 1, args[1].LastIndexOf("-") - args[1].IndexOf("-") - 1); account[1] = args[1].Substring(args[1].LastIndexOf("-") + 1); } else account[0] = args[1]; Marked as answer by temlehdrol Friday, November 0
