Default Values Table (C# Reference)

The following table shows the default values of value types returned by the default constructors. Default constructors are invoked by using the new operator, as follows:

int myInt = new int();

The preceding statement has the same effect as the following statement:

int myInt = 0;

Remember that using uninitialized variables in C# is not allowed.
