How can I just get the base filename from this C# code?

Question

I have the following code:

string[] files = Directory.GetFiles(@"C:\Notes", "*.txt", SearchOption.TopDirectoryOnly);
foreach(string file in files)

When I check the contents of file it has the directory path and extension. Is there a way I can just get the filename out of that?

Answer 1

You can use theFileInfo class:

FileInfo fi = new FileInfo(file);
string name = fi.Name;

If you want just the file name - quick and simple - use Path :

string name = Path.GetFileName(file);

Answer 2

您可以使用以下方法： Path.GetFileName(file)

Answer 3

System.IO.FileInfo f = new System.IO.FileInfo(@"C:\pagefile.sys");  // Sample file.
System.Windows.Forms.MessageBox.Show(f.FullName);  // With extension.
System.Windows.Forms.MessageBox.Show(System.IO.Path.GetFileNameWithoutExtension(f.FullName));  // What you wants.

Answer 4

如果您需要去除扩展名、路径等，您应该将此字符串填充到FileInfo并使用其属性或使用Path类的静态方法。
