Question

我在IDE SharpDevelop 上试过这个，而不是在visual studio上。我正在使用这样的命名空间：

using System.Data.OleDb;

但是它向我显示以下错误：

'Data' does not exist in the namespace 'System'(are you missing an assembly reference?)(CS0234)

Answer 1

收听编译器：您可能缺少对项目中System.Data程序集的引用。您需要使用Add Reference...菜单中的Project对话框添加该引用。

Answer 2

添加参考，然后搜索rgba(0,0,0,0)并使用

添加到您的程序中
