     string no3 = txtOSIInterestFromDebent.Text;
     txtOSITotalIncome.Text = (no1 + no2 + no3);

}

推荐答案

int number1 = 0;
int number2 = 0;
int number3 = 0;
int.TryParse(OSIInterstFromBank.Text, out number1);
int.TryParse(txtOSITDSFromBank.Text, out number2);
...

string + string = stringstring  <br />
int + int + int = SumOf3int<br />
number + number = SumOf2numbers

您看到我要告诉"您的内容吗?

要添加3个数字，您需要声明数字变量，然后将其转换为字符串.

Do you see what i''m trying to "tell" you?

To add 3 numbers you need to declare number variable, then convert it into string.

int no1 = Convert.ToInt32(txtOSIInterstFromBank.Text);
int no2 = Convert.ToInt32(txtOSITDSFromBank.Text);
int no3 = Convert.ToInt32(txtOSIInterestFromDebent.Text);
int no4 = (no1 + no2 + no3);

txtOSITotalIncome.Text=no4.ToString();
