Array.Initialize Method

Initializes every element of the value-type Array by calling the default constructor of the value type.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public void Initialize()

This method is designed to help compilers support value-type arrays; most users do not need this method. It must not be used on reference-type arrays.

If the Array is not a value-type Array or if the value type does not have a default constructor, the Array is not modified.

The value-type Array can have any lower bound and any number of dimensions.

This method is an O(n) operation, where n is Length.

Caution noteCaution

You can use this method only on value types that have constructors; however, value types that are native to C# do not have constructors.
