Question

我收到了这个错误，你能帮帮我吗？提前谢谢

过程或函数'ACMS_add'需要参数'@ACMS_doc_name'，这是未提供的。

    bool status = false;
    ACMS_core.settings.ACMS_global_settings Conn = new ACMS_core.settings.ACMS_global_settings();

    SqlCommand cmd = new SqlCommand("ACMS_add", conn);

Answer 1

在初始化所有属性后，您应该调用您的方法：

acmsAdd.ACMS_Number = docNumber.Text.Trim();
//acmsAdd.ACMS_Date = Convert.ToDateTime("2013-01-10 19:08:12.300");
acmsAdd.ACMS_Type = Convert.ToInt32(docType.SelectedValue);
acmsAdd.ACMS_doc_name = DocUpload.FileName.ToString();
acmsAdd.ACMS_doc_file = DocUpload.FileBytes;
acmsAdd.ACMS_doc_mime_type = DocUpload.PostedFile.ContentType;
acmsAdd.ACMS_doc_ext = file_ext;

和last（因为它正在执行存储过程）：

acmsAdd.ACMS_add(Page.User.Identity.Name);

更好的方法是更改方法的签名，以便必须提供所有参数。

Answer 2

在您的程序代码中，您有以下内容.....

@ACMS_Number as nvarchar (50),
--@ACMS_Date as datetime,
@ACMS_Type as int,
@enrty_user as nvarchar (50),
@ACMS_doc_name  nvarchar (250),         
@ACMS_doc_file image ,
@ACMS_doc_ext nvarchar(50),
@ACMS_doc_mime_type varchar(250)

现在我不是C＃的用户，但我注意到你的doc_file_name和其他一些行中没有“AS”子句......

你认为这可能是问题吗？
