C# how do you create a method that passes an array as an argument?

private bool DisplayErrorMessages(String array1[], String array2[])

Intellisense doesn't show array1 as available and VS2010 has the variable underlined in red

Unlike in C++, in C# you have to put the square brackets at the end of the Type :

private bool DisplayErrorMessages(String[] array1, String[] array2)

As Rob showed, you've got your square brackets in the wrong place.

However, you should understand that this isn't just about method parameters - it's everywhere you declare an array type variable. For example, local variables:

// Valid
String[] x = null;

// Invalid
String x[] = null;

It makes more sense this way IMO - it puts all the type information in one place. Why would you want to specify it "around" the variable? :)

See chapter 12 of the C# 4 spec for more about arrays in general, including "array types" (12.1).
