Question

C#中调用方法提示类型转换不了

private void Form1_Load(object sender, EventArgs e) { Person ZhangSan = new Person() ZhangSan.age = "ZhangSan"; this.textBox1.Text = ZhangSan.say(); } } public class Person { public string name; public int age; public string say() { return "中华"; } } }如题,当我把实例中的ZhangSan.age改成.name就能调用下面的方法了,但改成age为什么不可以呢,显示类型不对,求解

private void Form1_Load(object sender, EventArgs e) { Person ZhangSan = new Person() ZhangSan.age = "ZhangSan"; this.textBox1.Text = ZhangSan.age.ToString(); //输出年龄 // this.textBox1.Text = ZhangSan.name; //Name } } public class Person { public string name; public int age; public string say() { return "中华"; } }
