using System;

        }



        }

代码中有HTML实体,必须将其转换回实际字符

例如:

if (a >= 50 & a < 60 & Convert.ToInt64(textBox2.Text) >= 50)
应该是:

if (a >= 50 & a < 60 & Convert.ToInt64(textBox2.Text) >= 50)
if(a>=50&a<60&Convert.ToInt64(textBox2.Text)>=50)
私有无效按钮1\u单击(对象发送者,事件参数e)
{
双a;
a=((Convert.ToInt16(textBox1.Text)*0.4)+(Convert.ToInt16(textBox2.Text)*0.6));
如果(a>=50&&a<60&&Convert.ToInt64(textBox2.Text)>=50)
{
label4.Text=“Geç;ti”;
label5.Text=“CC”;
textBox3.Text=a.ToString();
}
其他的
{
label4.Text=“KALDI”;
标签5.Text=“FF”;
textBox3.Text=a.ToString();
}
}
私有无效按钮2\u单击\u 1(对象发送者,事件参数e)
{
textBox1.Text=“”;
textBox2.Text=“”;
textBox3.Text=“”;
label4.Text=“硬质合金”;
label5.Text=“Sonuc”;
}

”。。?这些东西在那里做什么?你从网上复制/粘贴了这些代码吗?
