未能找到带参数的非泛型方法
逻辑层方法如下：
[System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Insert, true)]
//public bool AddcalMainRecords(string? equipment_Name,int Use_Place_ID,DateTime Cal_Date,DateTime Due_Date,int Cal_Cycle_ID,string? Vender,string? Brand,string? Model,string? Serial_NO,string? Accuracy,string Class,int Project_ID,int Process_ID,string Status,string WI_NO,string? Drawing_NO,int? Renter_ID,DateTime? Rent_Date,int Sign_ID,string? Remark)
public bool AddcalMainRecords(string equipment_Name, int Use_Place_ID, DateTime Cal_Date, DateTime Due_Date, int Cal_Cycle_ID, string Vender, string Brand, string Model, string Serial_NO, string Accuracy, string Class, int Project_ID, int Process_ID,string Status, string WI_NO, string Drawing_NO, int Renter_ID,DateTime Rent_Date,int Sign_ID,string Remark)
{
// 新建一个calMainRecordsRow实例
cal.calMainRecordsDataTable mycals=new cal.calMainRecordsDataTable();
cal.calMainRecordsRow mycal=mycals.NewcalMainRecordsRow();
//mycal.Equipment_Name = equipment_Name;
if (equipment_Name == null) mycal.SetEquipment_NameNull(); else mycal.Equipment_Name = equipment_Name;
if (Vender == null) mycal.SetVenderNull(); else mycal.Vender = Vender;
if (Brand == null) mycal.SetBrandNull(); else mycal.Brand = Brand;
if (Model == null) mycal.SetModelNull(); else mycal.Equipment_Name = equipment_Name;
if (Accuracy == null) mycal.SetAccuracyNull(); else mycal.Accuracy = Accuracy;
if (Drawing_NO == null) mycal.SetDrawing_NONull(); else mycal.Drawing_NO = Drawing_NO;
//少了Renter_ID和Rent_Date
if (Remark == null) mycal.SetRemarkNull(); else mycal.Remark = Remark;
mycals.AddcalMainRecordsRow(mycal);
int rowsAffected = Adapter.Update(mycals);
// 如果刚好新增了一条记录，则返回true，否则返回false
return rowsAffected == 1;
}
在表现层插入数据的时候，提示：“/WebSite2”应用程序中的服务器错误。

[解决办法]
ObjectDataSource执行你的AddcalMainRecords(....)
如果是双向绑定的话,(也就是默认状态时)
AddcalMainRecords中对数据字段的名称必须和数据表的名称相同!
仔细检查你的AddcalMainRecords(....)中的字段名!!
[解决办法]
看看看看ObjectDataSource的参数列表，是否与字段一致
[System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Insert, true)]
public bool AddProduct(string productName, int? supplierID, int...)
{
}
