                showPro(xueTiao);
                
            }
            MessageBox.Show("满了");        }    }
}
进度条

Answer 1

不建议这样弄，这样弄即使有递增过程也是假的，建议你的 xueTiao++;放到实际业务处理完成后

Answer 2

while (true)
            {
                //System.Threading.Thread.Sleep(500); 此处可以加这句
                progressBar1.Value += 1;
                if (progressBar1.Value>=progressBar1.Maximum)
                {
                    return;
                }
            }

Answer 3

界面要刷新吧，在private void showPro(int value)         
{             
this.progressBar1.Value = value;             
this.label1.Content = value + "%";    
Application.DoEvents();//加这条，将消息给处理显示到界面上System.Threading.Thread.Sleep(1000);//停止一秒后继续+           } 

Answer 4

错误1“System.Windows.Application”并不包含“DoEvents”的定义报错啊！没有这个方法貌似

Answer 5

你是错误1“System.Windows.Application”并不包含“DoEvents”的定义报错啊！没有这个方法貌似

可能少了引用吧，百度下Application.DoEvents
顺便说下，这个方法界面还是会卡，毕竟是单线程的，用委托的方法界面会流畅些。
