How do I avoid getting a 'System.NullReferenceException' when using STREAM_TYPE_DEPTH in C#?

[tross3]

I am using C#, STREAM_TYPE_COLOR works fine, and I can see an image, but when I try to use STREAM_TYPE_DEPTH it crashes and tells me it is null. Also, the infrared light does not come on. It is not a problem with the camera though because the depth works fine in the Realsense Viewer program.

Are you using Unity and the RealSense Unity Wrapper for your project, please?

Thanks for the response. No, I'm not Unity, just C# and the C# wrapper.

With a NullReferenceException, I would typically expect it to be related to a reference that is being called but its location has not been defined.

For example, I might ask a program for the value of a variable called MartysNumber, but if I have not told my program where the variable can be found then a NullReferenceException may occur.

It is most likely to occur if the reference being called is stored in a different script. ​
