c#-4.0 - Adding a number at the end of the directory C#

Question

I want to add a number to the end of the directory for example, if the directory was called test, I want the other directory to be made test1 and then test2.

So basically, I want to make a directory which carries on from the previous by putting a number at the end. So it checks which directory was the last one e.g. Test1 and makes Test2

Thanks.

Answer 1

这很简单：您从数字开始"test"并附加数字，直到找到一个不存在的名称：

var baseName = "test";
var name = baseName;
int i = 1;
while(Directory.Exists(name))
{
    name = baseName + i;
    ++i;
}

return name;
