Hi ,

You must iterate over string array and convert each element to int and add it to your int array.

TArray<FString> StringArray;
StringArray.Add("100");
StringArray.Add("1");
StringArray.Add("2");

TArray<int32> IntArray;
for (auto& Str : StringArray)
{
	IntArray.Add(FCString::Atoi(*Str));
}

Best regards,

Just to add to 's thing, depending on what you’re doing with the array and how frequently you can always just Atoi when you actually want to use your strings as ints also.
