How do I quicky fill an array with a specific value?

问题:

Array.Clear() fills the arrays with the default value (zero for integers), I would like to fill it using -1 for example.

Thanks.

The other way is:

int[] arr =  Enumerable.Repeat(-1, 10).ToArray(); Console.WriteLine(string.Join(",",arr));

I am not aware of such a method. You could write one yourself, though:

public static void Init<T>(this T[] array, T value) {     for(int i=0; i < array.Length; ++i)     {         array[i] = value;     } } 

You can call it like this:

int[] myArray = new int[5]; myArray.Init(-1);
