所有枚举项目到字符串(C#)

Question

如何将所有元素从枚举转换为字符串？

假设我有:

public enum LogicOperands {
        None,
        Or,
        And,
        Custom
}

我要归档的是:

string LogicOperandsStr = LogicOperands.ToString();
// expected result:  "None,Or,And,Custom"

Answer 1

string s = string.Join(",",Enum.GetNames(typeof(LogicOperands)));

Answer 2

你必须做这样的事情:

var sbItems = new StringBuilder()
foreach (var item in Enum.GetNames(typeof(LogicOperands)))
{
    if(sbItems.Length>0)
        sbItems.Append(',');
    sbItems.Append(item);
}

或者在Linq:

var list = Enum.GetNames(typeof(LogicOperands)).Aggregate((x,y) => x + "," + y);
