Character Type: Assign a value to the character type variable (prefix \ U) using a hexadecimal escape character (prefix \ x) or Unicode notation ). It can be understood as"The displayed declaration converts a hexadecimal integer to a char character", Because C # cannot convert the integer hermit to a character char. For example, char c = '\ x0032 ';//Char c = '\ u0032 ';// TestCode: private void

Character type: Assigns a value (prefix \u) to a character variable by a hexadecimal escape character (prefix \x) or Unicode notation. In fact, it can be understood that "the display declared a 16-bit integer conversion to char" because C # cannot convert an integral hermit to char Char such as: Char c= ' \x0032 '; //Char c= ' \u0032 '; // Test code: private void Button1_Click (object sender, EventArgs e){

Therefore, we should use int for storage, and perform some processing on the id during display, so that it is easy to tell which table the id belongs. A database table usually has an auto-incrementing primary key named id, whose field type is int. Advantage: The int type can be used for auto-increment, saving storage space than the character type.Disadvantage: id is a numeric type. when you want to query the data corresponding to an id, it is difficult to determine which data table is based on
