How come System.IO.File is returning false when the file does exist?

Question

I'm using System.IO.File.Exists to check if a file exists. However, it's returning false for a file that I know exists. The code is the following:

Assert.IsTrue(System.IO.File.Exists(@"\ImportRepositoryTest\Version2.xml"));

How come System.IO.File is returning false when the file does exist?

Answer 1

尝试

Assert.IsTrue(System.IO.File.Exists(Path.Combine(TestContext.TestDeploymentDir,  @"\ImportRepositoryTest\Version2.xml")));

Answer 2

Change it to Assert.IsTrue(System.IO.File.Exists(@".\\ImportRepositoryTest\\Version2.xml")); (with a ".") and double check to see if you marked your file as "copy always".
