如何在不加载文件扩展名的情况下将文件名作为列表框项加载到列表框中？

Question

我加载的插件必须加载到左侧的列表框中，并且必须加载它们而不使用文件扩展名。

所以

  

“FirstPlugin.dll”

将加载为

  

“FirstPlugin”

When I load the file name without extension in the code I tried, either it loads just the name and does not execute or it just loads the file name with the extension.

这是背后的代码：

如何将文件名放入列表框并在没有扩展名的情况下工作？

Answer 1

您应该使用Path.GetFileNameWithoutExtension()方法，例如

result = Path.GetFileNameWithoutExtension(fileName);

看起来你已经收到了它，但在列表框中添加了错误

   lbFiles.Items.Add(System.IO.Path.GetFileName(filename));

更改

var ext = System.IO.Path.GetFileNameWithoutExtension(filename);
lbFiles.Items.Add(ext);
