Convert.ToInt32(char)方法用于將特定的char值轉換為其等效的整數(int 32帶符號的數字)(也稱為ASCII值)。

Syntax:

句法：

int Convert.ToInt32(char value);

It accepts a char value/variable as an argument and returns its equivalent signed integer.

它接受一個char值/變量作為參數，并返回其等效的帶符號整數。

Example:

例：

Code:

碼：

using System; using System.Text;namespace ConsoleApplication3 {class Program{static void Main(string[] args){char a = 'A'; //uppercase Achar b = 'z'; //lowercase zConsole.WriteLine("value of a: {0}, type of a: {1}", a, a.GetType());Console.WriteLine("value of b: {0}, type of b: {1}", b, b.GetType());//converting to Int32 & printing values & typesConsole.WriteLine("value: {0}, type: {1}", Convert.ToInt32(a), Convert.ToInt32(a).GetType());Console.WriteLine("value: {0}, type: {1}", Convert.ToInt32(b), Convert.ToInt32(b).GetType());//hit ENTER to exitConsole.ReadLine();}} }

Output

輸出量

value of a: A, type of a: System.Char value of b: z, type of b: System.Char value: 65, type: System.Int32 value: 122, type: System.Int32
