Assign: Object reference not set to an instance of an object. errror

bu şekilde hata alıyorum. Yardımcı olur musunuz?

valueA and/or valueB have not been assigned a value, so they are nothing. Not initialized.

Also, don’t use GenericValue. Set the variable type correctly - string, int, or whatever the value will be.

There were several reasons why this error Object reference not set to an instance of an object comes are listed below:

  • The null value of variable or argument
  • A null value for any activity from which you are getting the text.
  • Maybe you have created duplicate variables.
  • Import arguments are not updated.

Conclusion: Double-check the types of the variables. You may consider changing their type to System.String or System.Int32 .

Let us know if this helped.

As I said earlier, in the Variables section, check the types of the A, B, and C variables. Set them to Int32.
