问题描述

我的程序中有一个带遮罩的文本框，用于插入资金.
如何将这个被屏蔽的文本框求和到另一个文本框?我想将金额添加到用户添加的金额中.

Hi,

I have a masked textbox in my program to insert money.
How to sum this masked textbox to another textBox? I want sum to the money where the user added it.

推荐答案

将文本框的文本值转换为十进制

convert your text value of text box to decimal

更改Mask 属性-请参见此处 [ ^ ].

Change the Mask property - see here[^].

//You first convert into int or long. Well You are saying its money so better use float or double data types.
//here is the code. I prefer double.
if (maskedTextBox1.Text != null)//Cheak if textbox has value or not. If value present then convert it to double.
{
  double money=Convert.ToDouble(maskedTextBox1.Text)+Convert.ToDouble(maskedTextBox1.Text);//converted into double data type. money is variable.
textBox1.Text=money.ToString();//.ToString() method is available for any varable, any function, any data type to convert it into string for displating in textbox or some thing.
}

转换两个值并添加它们.尝试一下.
为什么要加倍并浮动.因为钱是十进制格式.例如100.80

Convert the two values and add them thats it. Try it it works.
WHy double and float. Beacause money is in decimal format. for example 100.80
