推荐答案

您的应用程序中发生了未处理的异常.

填充:SelectCommand.连接属性尚未初始化"

这意味着您尝试打开SqlCommand对象时未建立SqlConnection并先将两者绑定在一起:这与在PC上安装.NET无关！
看看MSDN-它向您展示如何正确执行操作:填充来自DataAdapter的数据集 [ ^ ]

"Unhandled Exception has occurred in your application.

Fill: SelectCommand. Connection Property has not been initialized"

This means that you have tried to open a SqlCommand object without establishing a SqlConnection and tying the two together first: it has nothing to do with installing .NET on your PC!

Have a look at MSDN - it shows you how to do it properly: Populating a DataSet from a DataAdapter[^]
