推荐答案

使用

Use

Users = Split(Data, ","c)

或

or

Users = Split(Data, '','')

Split是Data的一种方法，它是一个字符串. Data不能是第一个参数.另外，定界符参数是字符数组，而不是字符串.
您不应使用"，而应使用string.Empty.

阅读 http://msdn.microsoft.com/en-us/library/system.string .split.aspx [ ^ ].

Split is a method of Data which is a string. Data cannot be a first parameter. Also, delimiter parameter is array of characters, not string.
You should not use "", use string.Empty.

Read http://msdn.microsoft.com/en-us/library/system.string.split.aspx[^].

—SA

Split 函数中的第二个参数是int或StingSplit options枚举，因此，"无效.

The second parameter in the Split function is either an int or a StingSplit options enumeration, so "," is invalid.
