Hi @ryoryo,

To initialize string array, use the below syntax.
new string(){}

Another suggestion is to use collection variable.

It happens when the number of elements specified in the array while initializing does not match the number of elements stored.

Try new string(1){} if the length is known.
Better way to use is collection when the length is not known.

In C#:
new List<int>() { 2, 3, 5, 7 };
new List<string>() {"abc","xyz"}

Arrays can be init as (you need to declare the size):
new int[2]{121,232}
new string[2] {"abc","xyz"}

In short, initiate just as you would in your C# program either using assign Activity or setting Default values while declaring in variables tab
