Array sizeWe can generally use sizeof (array name)/sizeof (array Element) to find the number of array elements, but it should be noted that when we need to call the function to handle the array, the length of the array is to be obtained before

First, the data types in C #. The two categories of the score type and the reference type.Value type: A value that stores data directly, stored in an in-memory stack (stack)Reference type: Stores a reference to a value that is actually stored as a

A value type can never be null, but when a column of data in a database is allowed to be empty, or a data type (reference type) in another language is a value type that corresponds to C #, it is possible to deal with a null value when it is
