In the first case, the problem will occur if you do not have the cursor stored as a Resource - if it is held as a separate file in your project, then you will get the null reference.

In the second case, check your CUR file - it isn't in Windows Cursor format. Did you rename a JPG, BMP or GIF and hope for the best?

To solve this issue , place your cursor file in the debug folder of the project and pass the filename like this:

C#

panel1.Cursor = new Cursor("in.cur");

Or
Pass the full path of the cursor file:

C#

panel1.Cursor = new Cursor("D:\\MyCursor\\in.cur");

Image format is not valid. The image file may be corrupted.
Parameter name: stream is coming. But the image is .cur format only also the file is in the debug folder.

Cursor have 2 overloads 1.Stream 2.string(filename), OP using string overload i.e again converted to the stream, better to use the stream to pass the .cur file.
