C#源代码—在windows窗体中添加一个名为lblShow的Lable控件3

using System;
using System.Windows.Forms;
namespace TestVariable
{
    public partial class TestOperator : Form
    {
        private void TestVariable_Load(object sender, EventArgs e)
        {
            int a, b = 5;
            char c1 = 'A';
            a = c1;                    //字符型转整型
            float x = 3;
            x += b;                     //整型转浮点型
            lblShow.Text = "a=" + a;    //整型转为字符串
            lblShow.Text += "\nx=" + x; //浮点型转为字符串
         }
    }
