Default Values Table for ASP.NET

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.
