new to C# - unable to get File.Copy to work

Question

This is a code sample from Microsoft, with a different file location, that just won't work:

 string fileName = "test1.txt";
 string sourcePath = @"C:\";
 string targetPath = @"C:\Test\";

 // Use Path class to manipulate file and directory paths.
 string sourceFile = System.IO.Path.Combine(sourcePath, fileName);
 string destFile = System.IO.Path.Combine(targetPath, fileName);

 System.IO.File.Copy(sourceFile, destFile, true);

It can't find the source file. If I set a break point, this is what I get:

    args    {string[0]} string[]
    fileName    "test1.txt" string
    sourcePath  "C:\\"  string
    targetPath  "C:\\Test\\"    string
    sourceFile  "C:\\test1.txt" string
    destFile    "C:\\Test\\test1.txt"   string

So it looks like it is doubling the backslashes even though a verbatim string is used. (there is no doubt that I have a test1.txt file in C:) Any ideas? Thanks!

Answer 1

doubling of backslashes is correct, I think your problem is file name. try to read the file without that operations, but before see if you "Hide Extenstions for known Type" if you do than filename should be test1.txt.txt :)
