通过从csv文件中获取表将DateTime值分配给变量

Question

DateTime someDate = DateTime.Parse(row[table.Columns[1].ColumnName].ToString());

Suppose if the file has no date in specific column and I want to pass a null value, how can I achieve this? 假设如果文件在特定列中没有日期，而我想传递一个空值，我该如何实现呢？

I want to achieve this in one line ... also note that I am using C# ASP.NET MVC ... Thanks. 我想在一行中实现这一目标……还请注意，我正在使用C＃ASP.NET MVC……谢谢。

Nullable DateTime could be helpful: 可空的DateTime可能会有所帮助：

DateTime ? dateTime;

Then you can use it like a normal DateTime object or nullify it: 然后，您可以像普通的DateTime对象一样使用它或将其无效：

dateTime = System.DateTime.Now;
dateTime = null;
