                  问题描述

                  我的表单上有一个 listView.我想在程序运行期间添加一些东西.

                  I have a listView on my form. I want to add stuff to it durring the program is running.

                  这是我使用的代码

                  public void FillList(string[] Name,int[] empty,int[] Population,int[] Max,int[] Check,int size)
                  {
                      if (this.InvokeRequired)
                      {
                          this.Invoke((MethodInvoker)delegate
                          {
                              for (int i = 0; i < size; i++)
                              {
                                  ListViewItem item = new ListViewItem(Name[i]);
                  
                                  item.SubItems.Add(empty[i].ToString); //error
                                  item.SubItems.Add(Population[i].ToString); //error
                                  item.SubItems.Add(Max[i].ToString);   //error
                  
                                  if (Check != 1)
                                      item.SubItems.Add("No");
                                  else
                                      item.SubItems.Add("Yes");
                                  listView1.Items.Add(item);
                              }
                          });
                      }
                  }
                  

                  参数必须是字符串,我尝试了 .ToString,但我明白了:

                  the parameter must be string and I tried .ToString, but I get this:

                  参数1":无法从方法组"转换为字符串"

                  Argument '1': cannot convert from 'method group' to 'string'

                  推荐答案

                  你缺少方法调用的括号:

                  You are missing the parentheses of the method call:

                  ToString()

                  没有括号,表达式是一个方法组——即对一个或多个重载方法的引用.

                  Without the parentheses, the expression is a method group— that is, a reference to one or more overloaded methods.
