问题 What is the easiest way to get the drive letter from a URI type file path such as file:///D:/Directory/File.txt I know I can do (path here is a string containing the text above) path = path.Replace(@"file:///", String.Empty); path = System.IO.Path.GetPathRoot(path); but it feels a bit clumsy. Is there a way to do it without using String.Replace or similar? 回答1: var uri = new Uri("file:///D:/Directory/File.txt"); if (uri.IsFile) { DriveInfo di = new DriveInfo(uri.LocalPath); var driveName = di

问题 Is there a way to programmatically get the FileInfo/Path of the ildasm.exe/ilasm.exe executables? I'm attempting to decompile and recompile a dll/exe file appropriately after making some alterations to it (I'm guessing PostSharp does something similar to alter the IL after the compilation). I found a blog post that pointed to: var pfDir = Environment.GetFolderPath(Environment.SpecialFolders.ProgramFiles)); var sdkDir = Path.Combine(pfDir, @"Microsoft SDKs\Windows\v6.0A\bin"); ... However,

问题 Is it possible to get the size of a file in C# without using System.IO.FileInfo at all? I know that you can get other things like Name and Extension by using Path.GetFileName(yourFilePath) and Path.GetExtension(yourFilePath) respectively, but apparently not file size? Is there another way I can get file size without using System.IO.FileInfo ? The only reason for this is that, if I'm correct, FileInfo grabs more info than I really need, therefore it takes longer to gather all those FileInfo's

问题 I need to put a lot of filepaths in the form of strings in Python as part of my program. For example one of my directories is D:\ful_automate\dl . But Python recognizes some of the characters together as other characters and throws an error. In the example the error is IOError: [Errno 22] invalid mode ('wb') or filename: 'D:\x0cul_automate\\dl . It happens a lot for me and every time I need to change the directory name to one that may not be problematic. 回答1: The \ character is used to form

So if you place your help folder in

问题 I'm trying to write a static member function in C# or find one in the .NET Framework that will re-case a file path to what the filesystem specifies. Example: string filepath = @"C:\temp.txt"; filepath = FileUtility.RecaseFilepath(filepath); // filepath = C:\Temp.TXT // Where the real fully qualified filepath in the NTFS volume is C:\Temp.TXT I've tried the following code below and many variants of it and it still doesn't work. I know Windows is case-insensitive in general but I need to pass
