能不能根据复选框的名称对多个复选框进行循环

Question

for (int i = 1; i < 13; i++)
                    {
                        if (((CheckBox)("chk"+i.ToString())).Checked)
                        {
                            nn+=i.ToString() + "月销售量;
                                
                          }                     
                    
                    
                    错误 1 无法将类型“string”转换为“System.Windows.Forms.CheckBox”其中有12个复选框 name一次是 chk1 chk2 chk3 ……
取出名称后强制转换能够有check属性 但就是编译报错

Answer 1

不能这么做，你不能把string类型转换为checkbox类型
但可以通过遍历控件搞定，

            foreach (System.Windows.Forms.Control  item in this.Controls)
            {
                CheckBox chk = item as CheckBox ;
                if (chk != null)
                {
                    Console.WriteLine(chk.Name);
                    if (chk.Checked)
                    {
                        Console.WriteLine("{0} is checked .", chk.Name);
                        //nn+=chk.Text  + "月销售量; 
                    }
                }
            }
