如何将数字与字符串值相加 [英] How to Add number with string values

问题描述

如何从字符串中添加整数..

例如，

我想将一个数字与字符串值相加.
rdr("Code")的值为"AB"

最后，我想得到的结果是AB + 1，AB + 2这样的

例如:

昏暗的Cnt为整数= 1

Cnt = rdr("code")+ 1 ==>从字符串到int的错误转换

此处有任何问题...?

Hi,

How to add integer number from string..?

For Example,

I want to add one number with String values.
rdr("Code") value is "AB"

At end i want to get the result is AB+1,AB+2 like that

Ex:

Dim Cnt as integer = 1

Cnt = rdr("code") + 1 ==> Getting error conversion from string to int

Any problem here...?

推荐答案

如果要输出为"AB + 1"，"AB + 2"，则需要将字符串附加为

If you want to output as "AB+1", "AB+2", then you need to append strings as

for (i=1;i<=5;i++)
{
  String op;
  op = rdr("code") + "+" + i.ToString();
}

您不能像现在那样用任何整数添加字符串"AB".

You cannot add string "AB" with any integer, as you are doing now.
