Hi @Happydayyy
This statement sets the value of the variable that you have in Assign Activities to an empty string, which means it doesn’t contain any characters.
Assign Activity:
→ The “Assign” activity is used to assign a value to a variable or to update the value of an existing variable.
→ Left side (Save To): This is where you specify the variable or property to which you want to assign a value. You can select an existing variable or create a new one directly within the “To” field.
→ Right side (Value to Save): This is where you specify the value you want to assign to the variable or property. It can be a constant value (such as a string, number, Boolean), the result of an expression, or the value of another variable.
Hope you understand!!
Regards
Hi @Happydayyy ,
I believe you are asking, what does assign mean and how it works
So ASSIGN means Allocating/Giving some value to a variable.
It means, previous developer assigned empty value to a string variable to avoid any NullReferenceException in the code.
This could have been handled with default value assignment in Variable panel instead of plotting so many Assign activities.
You can use “” or String.Empty also.
In terms of functionality, they are equivalent, and you can use either of them to represent an empty string in your code. However, string.Empty is more self-descriptive and can improve code readability in some cases, while "" is more concise and commonly used. The choice between them often depends on personal preference and the coding style of your team.
Thanks,
