删除字符串的最后一个字符 [英] Delete last char of string
问题描述
我在一个链接到数据库的列表中检索了大量信息。
I am retrieving a lot of informations in a list, linked to a Database .
我想要创建一个组字符串,网站。
I want to create a string of groups, for someone who is connected to the website.
我用它来测试...但这不是动态的,所以真的很糟糕:
I use this to test ... But this is not dynamic so really bad :
string strgroupids =6;
string strgroupids = "6";
现在我想使用这个。但返回的字符串类似于1,2,3,4,5,
I want to use this now . But the string returned is something like 1,2,3,4,5,
//groupIds.ForEach((g) =>
//{
// strgroupids = strgroupids + g.ToString() + ",";
// strgroupids.TrimEnd(',');
//});
//strgroupids.TrimEnd(new char[] { ',' });
我要删除,后5,但它绝对不工作..
有人帮助我?
I want to delete the , after the 5 but it's definitely not working .. Can someone help me?
非常感谢。
