我有问题。我想制作插入方法。我已经检查了所有代码与另一种方法相同的另一种方法是成功的。但在下面的代码中，它总是抛出错误
你可以帮帮我吗？我有2天的错误对象引用未设置为对象的实例。
这是控制器代码
public ActionResult MultipleCommand(NCRForm ncr, string Command)

if (Command == "Submit")

int a = 001;
var filename = Path.GetFileName(ncr.attachment.FileName);
try

}
if (!(ncr.attachment.ContentType == "file/doc" || ncr.attachment.ContentType == "file/docx" || ncr.attachment.ContentType == "file/pdf"))
