错误CS1061"...不包含定义且没有扩展方法...接受类型为“的第一个参数" [英] Error CS1061 “...Does Not Contain Definition and No Extension Method...accepting a first argument of type ” could be found
问题描述
.NET Visual Studio是我的新手，正在构建Windows窗体应用程序.
I am new to .NET visual studio, building windows Form Application.
尝试构建解决方案时，出现以下错误.我不确定是否与文件'SuperAdventure.SuperAdventure'或未指定的控件有关.
I had the following error described below, when trying to build a solution. I am not sure if it has to do with something related to the file 'SuperAdventure.SuperAdventure' or a control that was not specified.
'SuperAdventure.SuperAdventure'不包含" label5_Click "的定义和没有扩展方法"label5_Click"，且接受第一个参数可以找到"SuperAdventure.SuperAdventure"类型(您是否缺少using指令或程序集引用?)
'SuperAdventure.SuperAdventure' does not contain a definition for 'label5_Click' and no extension method 'label5_Click' accepting a first argument of type 'SuperAdventure.SuperAdventure' could be found (are you missing a using directive or an assembly reference?)
这是错误代码，该错误代码在标记行的代码下显示红色的波浪状/线条.
This is the error code with the error showing a red squiggly/line under the code in the marked line.
// lblExperience
//
this.lblExperience.AutoSize = true;
this.lblExperience.Location = new System.Drawing.Point(110, 73);
this.lblExperience.Name = "lblExperience";
this.lblExperience.Size = new System.Drawing.Size(35, 13);
this.lblExperience.TabIndex = 6;
this.lblExperience.Text = "label7";
this.lblExperience.Click += new System.EventHandler(this.label5_Click); // <-- squiggly line here
并在输出上给出以下内容:
and on the output it gives this:

推荐答案
快速解决方案:删除this.lblExperience并重新创建.
Quick solution: Delete this.lblExperience and create it again.
该控件似乎找不到其click事件处理程序，并且在不变得太复杂的情况下，先删除该控件，然后双击该控件将创建一个新的处理程序并正确绑定它.
The control can't seem to find its click event handler, and without getting too complex, deleting the control then double-clicking on it will create a fresh handler and correctly bind it.
其他快速解决方案:删除该行.但是然后您就没有针对其click事件的处理程序了，这可能是有意的.
Other quick solution: Delete that line. But then you have no handler for its click event, which may be intentional.
