将List转换为单个字符串

Question

尝试将List属性转换为字符串，任何想法？

public class ContactLog
{
     public string To { get; set; }
     public string Message { get; set; }

     public string FormattedMessage
     {
         get { return To+ ',' + Message; }
     }
 }

public void SendBatch(List<ContactLog> logs)
{
    //Problem Line
    string messages = CreateBulkMessage(logs.Select(o => o.FormattedMessage));
}
public string CreateBulkMessage(string message)
{
    //Do Stuff
}

您可以使用string.Join将Select的结果合并为一个string：

string messages = string.Join(", ", logs.Select(o => o.FormattedMessage));
