C＃如何创建将数组作为参数传递的方法？

Question

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

Intellisense不会将array1显示为可用，并且VS2010的变量用红色下划线

Answer 1

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

Answer 2

与C ++不同，在C＃中，必须将方括号放在Type的末尾：

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

Answer 3

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).
