如何添加两个字符串值并将其显示为字符串值 [英] how to add two string value and display it in string value

问题描述

tot = int.Parse(tot + amtusd).ToString();

我要加法不要串联.

i want addition not concatenation.

推荐答案

尝试一下，

Try this,

tot = (Convert.ToInt32(amtusd) + Convert.ToInt32(tot)).ToString();

或

or

tot = (int.Parse(amtusd) + int.Parse(tot)).ToString();

尝试一下:

Try this :

string tot = (int.Parse(tot) + int.Parse(amtusd)).ToString();

其中一种方式:

One of the ways:

 // Sample addition of string and a number
string concatenatedString = String.Empty;
string someString1 = "StringABC";
string someString2 = "1234";
int someNumber = 678;
concatenatedString =  someString1 + someString2 + someNumber.ToString();

现在，像这样串联起来的几个字符串就可以了.如果要串联很多，则应使用 StringBuilder [ ^ ].

更新:
如果要添加数字(以字符串格式)，然后再次将其转换为字符串，则:
对于数字字符串，请阅读:Int.Parse或Convert.ToInt32
要将数字转换为字符串，请阅读:ToString()方法.

Now, couple of strings if concatenated is fine like this. If you want to concatenate lots of them, then you should use StringBuilder[^].

UPDATE:
If numbers (in string format) to be added and then again converted to string then:
for string to numbers, read: Int.Parse or Convert.ToInt32
for converting numbers to string, read: ToString() method.
