I'm trying make a program where you call operations like addition from classes.
I don't know why there's an error:
public string Add() {
string AdditionTotal;
int num1 = int.Parse(txtFirstNumber.Text);
int num2 = int.Parse(txtSecondNumber.Text);
AdditionTotal = num1 + num2; //throws an error here
return AdditionTotal;
}
public string SetText {
get {
return txtFirstNumber.Text;
}
set {
txtFirstNumber.Text = value;
}
}
Try like this
AdditionTotal = (num1 + num2).ToString();
num1 and num2 both is an int and their sum is also an int
C# can't convert it directly from int to string .
you have to cast it pragmatically in order to assign.
AdditionTotal is of type of string and you are assigning int to it. Make AdditionTotal an int and return AdditionTotal.ToString()
The result of int + int is an int and you are trying to assign it to a string variable.
AdditionTotal should be an int and return type of method an int, or return AdditionTotal.ToString()
public int Add(int Total) {
int AdditionTotal;
int num1 = int.Parse(txtFirstNumber.Text);
int num2 = int.Parse(txtSecondNumber.Text);
AdditionTotal = num1 + num2; //throws an error here
return AdditionTotal;
}
AB= (A + B).ToString(); Resulted AB will store the sum of A and B (int) and convert it to string. AB will have sum of a and b but in string format like a=2,b=3 then AB="5".
