窗体很简单，就是一个按钮触发

准备运行

报错，发现是.value发现没有找到，搜了一顿之后发现，可能是.net框架的问题，因为我就在开始建项目的时候，.net框架5.0后面括号里面显示不支持。当时也不知道那是个啥，直接就下一步了，没想到这里挖坑了。

问题解决

1. 下载别的版本的.net框架

我下载了一个4.8.1版本的和6.0版本的，其实下载一个就好了。

2. 安装

等待安装之后，我本来想直接在项目——右键属性——应用程序——目标框架，里面去选择我刚刚安装的，但是我的里面就只有5.0和3.1，还都显示不支持（下图是我安装之后重新新建了一个才出来的）

3. 运行

运行结果很成功
