System.UnauthorizedAccessException in File.Create c#

Question

Edit: I noticed this doesn't happen when I just do: File.WriteAllText(@"C:\Users\(usr)\Documents\Test\Data\test.txt", "0"); without Globals.dmp so evidently it must be something with Path.Combine() I tried various variations of the composition but with same results.
I want to create a folder and a text file in my c# program made with Visual Studio. What I'm doing is having a check at Form Load to see if the file exists, and if it does not, create the file.
I'm doing it like this:

if(!File.Exists(Globals.dmp))
            {
                File.Create(Globals.dmp);
                File.WriteAllText(Globals.dmp, "0");
            }

The composition of globals.dmp is the following:

public static string dmp = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), Constants.dmp);

While Constants.dmp is like this:

public static string dmp = @"Test\Data\test.txt

This should work, but when I try to run it, Visual studio reports: System.UnauthorizedAccessException: 'Access to the path 'C:\Users\(usr)\Documents\Test\Data\test.txt' is denied.'The line that fails is: File.Create(Globals.dmp);
I tried putting File.SetAttributes(Globals.dmp, new FileInfo(Globals.dmp).Attributes | FileAttributes.Normal); above File.Create but the same thing happens. Any insight is greatly appreciated.

I solved the problem by adapting PathCombineAndCanonicalize1() from the second solution in this question

What I did is:

            public static string PathCombineAndCanonicalize1(string path1, string path2)
            { 
                string combined = Path.Combine(path1, path2);
                return combined;
            }
            public partial class ProgramDirectories
            {
                public static string directory = @"DillData\";
                public static string documentspath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
                public static string pathforfiles = PathCombineAndCanonicalize1(documentspath, directory);
                public static string sps = PathCombineAndCanonicalize1(pathforfiles, Constants.sps);
            }

With Constants.sps="text.txt";
And then I could easily do:

if (!Directory.Exists(ProgramDirectories.pathforfiles))
{
     Directory.CreateDirectory(ProgramDirectories.pathforfiles);
}

if(!File.Exists(ProgramDirectories.sps)
{
     File.WriteAllText(ProgramDirectories.sps, "0");
}

Run your visual studio as administrator and see it works or not.
