在批处理文件中将字符串转换为整数

Question

I have a variable read from a file: 我有一个从文件读取的变量：

%var%=13,145

I want to add this value to another value: 我想将此值添加到另一个值：

set /a %var%=%var%+5

but the result is 13+5 , not 13145+5 . 但是结果是13+5 ，而不是13145+5 。

How can I delete this "," from my string? 如何从字符串中删除此“，”？

Answer 1

Do not add commas. 不要添加逗号。

set var=13145

And also, when assigning a variable, don't place it around % 而且，在分配变量时，请勿将其放置在%附近

set /a var=%var% + 5   (Or simply set /a var += 5)

Test: 测试：

@echo off
set var=13145
set /a var=%var% + 5
echo %var%

Output: 输出：

Another solution is to remove those commas with substitution: 另一个解决方案是用替换删除那些逗号：

set var=13,145
set /a var=%var:,=% + 5
