C#: System.Diagnostics.Process.Start("Explorer.exe", @"/select" + FilePath). Can not open file when file's name is unicode character

Question

I want to open file's location with window Explorer. I am using C# with code

System.Diagnostics.Process.Start("Explorer.exe", @"/select," + FilePath)

it works well with simple English character, but it could not open the file's location if the file's name is Unicode character (Thia language).

Anyone could help please?

Answer 1

Try putting it in quotes:

System.Diagnostics.Process.Start("Explorer.exe", @"/select,""" + FilePath + "\"")

Answer 2

No trouble with this code snippet:

    static void Main(string[] args) {
        string path = @"c:\temp\លួចស្រលាញ់សង្សារគេ.DAT";
        System.IO.File.WriteAllText(path, "hello");
        string txt = System.IO.File.ReadAllText(path);
    }

Windows 7, the file is created and displays correctly in Explorer. You didn't document your operating system version so that's one failure mode, albeit a very small one. Much more likely is trouble with the file system that's mapped to your E: drive. Like a FAT32 volume on a flash drive or a network redirector. Ask questions about that, respectively, at superuser.com and serverfault.com. Do not forget to document those essential details.
