C＃清单 用定界符字符串 - C# List to string with delimiter

问题：

Is there a function in C# to quickly convert some collection to string and separate values with delimiter? C＃中是否有一个函数能够将某些集合快速转换为字符串并使用定界符分隔值？

For example: 例如：

List<string> names --> string names_together = "John, Anna, Monica" List<string> names -> string names_together = "John, Anna, Monica"
