formatting string in C#

Question

如何将此字符串列表转换为用引号引起来的逗号分隔值而没有任何转义符？

{"apple", "berry", "cherry"} => well, ""apple", "berry", "cherry""

Answer 1

If I understood you correctly,

"\"" + String.Join("\", \"", new string[]{"apple","berry","cherry"}) + "\"";

or, alternatively,

String.Format("\"{0}\"", String.Join("\", \"", new string[] {"apple","berry","cherry"}));

Hope this will do the job

var ar = new []{ "apple", "berry", "cherry" };
var separator = "\",\"";
var enclosingTag = "\"";
Console.WriteLine ( enclosingTag + String.Join(separator, ar) + enclosingTag );

Answer 3

If you are using C#:

using System;
string[] arr = new string[] { "apple", "berry", "cherry" };
string sep = "\",\"";
string enclosure = "\"";
string result = enclosure + String.Join(sep, arr) + enclosure;
