[英]C# Delete the nth item from a string
How would i go about deleting (not just replacing with a ' '
) The nth char of a string. 我将如何删除(而不仅仅是用
' '
代替)字符串的第n个字符。 Say i want to have Hello World
output Hllo World
any thing that could do this? 说我想让
Hello World
输出Hllo World
可以做到的任何事情?
With .Remove 用。删除
var removed = s.Remove(1, 1);
note, you can't change a string, you can only create a new string with the character removed. 请注意,您不能更改字符串,只能创建一个删除了字符的新字符串。
字符串类具有remove方法
var s = "abc".Remove(1,1); //will return ac
StringBuilder a = new StringBuilder("Hello World");
a.remove(1, 1);
string stringFlag = "ImAFlag";
var charList = stringFlag .Select(c => c.ToString()).ToArray();
charList.RemoveAt(0);
string newString = null;
foreach(var item in charList)
{
newString += item.ToString();
}
now the stringFlag is 现在stringFlag是
"mAFlag"
