Question

C#中怎么获得一个字符的ASCII码，以及怎么把ASCII码转化为相应的字符，小弟刚学，请教一下，谢谢

很感谢一楼的回答，但我感觉不直接（VB.NET中有Chr()和Asc()感觉用的很方便），有没有C#自带的方法来实现呀！

Answer 1

这么写就行，C#和C语言一样int和char是可以相互转换的

private void button1_Click(object sender, EventArgs e)
{
int i = 'A';
MessageBox.Show("A的ASCII码是:" + i.ToString());
int j = 78;
MessageBox.Show("ASCII码78对应的字符是:" + (char)j);
}

Answer 2

private void TestChar() {
char ch = ''a''; short ii = 65;
this.textBox1.Text = "";
this.textBox1.AppendText("The ASCII code of \''" + ch + "\'' is: " + (short) ch + "\n");
this.textBox1.AppendText("ASCII is " + ii.ToString() + ", the char is: " + (char) ii + "\n");
char cn = ''中''; short uc = 22478;
this.textBox1.AppendText("The Unicode of \''" + cn + "\'' is: " + (short) cn + "\n");
this.textBox1.AppendText("Unicode is " + uc.ToString() + ", the char is: " + (char) uc + "\n");
}
它的运行结果是

The ASCII code of ''a'' is: 97
ASCII is 65, the char is: A
The Unicode of ''中'' is: 20013
Unicode is 22478, the char is: 城
