为什么断点调式时可循环，F5直接运行，只输出一次

Question

代码中在发布内容做了一个循环发布，在设置断点调试的时候每一次循环都可以执行输出，但直接运行的时候却只输出了一次结果，不知道是哪方面的原因

Answer 2

                              if (tbloginurl.ToString().Trim() != "")
                              {
                                    string username;
                                    string url;
                                    string password;
                                    username = tbusername.Text;
                                    url = tbloginurl.Text;
                                    password = tbpassword.Text;
                                    login(username, url, password);
                                          for (int i = 0; i <10; i++)
                                          {
                                                
                                                send();
                                                                                                                                  }
                                          
                                      
                              }
                              else
                              {
                                    MessageBox.Show("登录网址不能为空");
                              }你确定这里的 } 是你少复制了？这个程序能跑起来么？

Answer 3

在for循环里执行send后适当延时一下。一般单步调试可执行，去掉断点就不行都是因为多线程或其他原因造成的，可以尝试用延时的方法去解决。

Answer 4

send();
后面加上 Thread.Sleep(5000);

Answer 5

send();
System.Threading.Thread.Sleep(3000);
