how can I use variable string parameter in dotnet test (Visual Studio 2022)

[Test]
public void MyTest(string MyString)
{
     Console.WriteLine(MyString);
}

and execute the test by command line with this variable string?

dotnet test "C:MyPathTest.dll" --filter "FullyQualifiedName=QualifyTest.ColorTest("This is my String")

Is it also possible to pass path names like “D:Thisismypath.txt” in the same way?

Should I use [TestCase] or [TestCaseSource] with included parameter instead and how?
I use NUnit 3.0

Thank you.
