NullReferenceException on an assignment line
Hi everyone.
I am confused because I am just assigning a null to my instance bug I am receiving NullReferenceException on the following line:
128 catch (Exception ex)
129 {
130 device = null;
131 }
The content of the exception is:
NullReferenceException: Object reference not set to an instance of an object
SampleScript.OnRawFrame (System.Int32 nSeq, System.Int32[] data) (at Assets/SampleScript.cs:130)
BioSignalPlux.CSharp.BaseDevice.Loop () (at Assets/BioSignalPlux.cs:180)
SampleScript.Update () (at Assets/SampleScript.cs:80)
And it happens randomly after 1 minute my code runs. Please help me figure out the problem.
It's because NullReferenceException is given when you try to use a variable that is null which means no value assigned. When you make it null and try to use it, it will give you that error.
Thank you! I know what is the meaning of this exception. For your information. if you read the line 130, I am not using it. I am only assigning.
Are you sure anything else also not using it? $$anonymous$$aybe something else was using it when you assigned it as null.
In that case, the exception would be different.
