FreeImage .NET Blank FileName when not constant

Question

Can somebody explain me please why FreeImage library is not recognizing my variable as a valid filename for the method Load, I tried the following code:

var fileName = "C:\\images\\myimage.tif";
            var dib = FreeImage.Load(FREE_IMAGE_FORMAT.FIF_TIFF, fileName, 0);

And it's not working, the object dib is always empty (the image is not being loaded), but when I tried the following code:

const string fileName = "C:\\images\\myimage.tif";
            var dib = FreeImage.Load(FREE_IMAGE_FORMAT.FIF_TIFF, fileName, 0);

The result is successful, the problem is that I need that image path value to be a normal variable (NOT const), because I work with different images each time, and this images could be anything.

How could I solve this issue, or it's a limitation of the library?

Thanks.

The first thing I see, you are setting the first example as a var instead of string. Define your variable as a string. I would try that, you dont need the const to make it work I don't believe.

string fileName = "C:\\images\\myimage.tif";
