我想为我做条形码控制器的产品创建条形码:
public ActionResult Index(BProduct model)
{
barcodecs objbar = new barcodecs();
BProduct objprod = new BProduct()
{
ProductName = model.ProductName,
Description = model.Description,
ImageUrl = model.ImageUrl,
BarCodeID = model.BarCodeID,
Barcode = objbar.generateBarcode(),
BarcodeImage = objbar.getBarcodeImage(objbar.generateBarcode(),model。 ProductName)
};
BProduct.InsertOnSubmit(objprod);
SubmitChanges();
return RedirectToAction( Mixxim_ICT, Home);
}
私有 void SubmitChanges()
{
throw new NotImplementedException();
}
静态 void Main( string [] args)
{
try
{
FutureFeature();
}
catch (NotImplementedException notImp)
{
Console.WriteLine(notImp.Message);
}
}
静态 void FutureFeature( )
{
// 尚未开发。
throw new NotImplementedException();
}
public ActionResult BarCode()
SqlConnection con = new SqlConnection( 数据源= ------- \\SQLEXPRESS;初始目录=存储;集成安全性= sspi);
string query = select * From Barcode 跨度>;
DataTable dt = new DataTable();
con.Open();
SqlDataAdapter sda = new SqlDataAdapter(query,con);
sda.Fill(dt);
con.Close();
IList model = new List();
for ( int i = 0 ; i < dt.Rows.Count; i ++)
{
var p = dt.Rows [i] [ BarCodeImage];
model.Add( new BProduct()
{
ProductName = dt.Rows [i] [ ProductName]。ToString(),
描述= dt.Rows [i] [ 描述]。ToString(),
Barcode = dt.Rows [i] [ Barcode1]。ToString(),
ImageUrl = dt.Rows [i] [ BarCodeImage]!= null ? data:image / jpg; base64, + Convert.ToBase64String(( byte [])dt.Rows[i][ BarCodeImage]):
}
);
}
return 查看(型号);
}
}
}
当我运行项目并点击时创建
i得到:ITCompany.dll中出现System.NotImplementedException类型的异常但未在用户代码中处理
查看您的代码:
静态 void Main( string [] args)
{
try
{
FutureFeature();
}
catch (NotImplementedException notImp)
{
Console.WriteLine(notImp.Message);
}
}
静态 void FutureFeature( )
{
// 尚未开发。
throw new NotImplementedException();
}
它所做的只是抛出一个NotImplementedException - 因为这就是你告诉它要做的所有事情! / BLOCKQUOTE>

I want to create Barcode for products that what i did barcode controller:
public ActionResult Index(BProduct model) { barcodecs objbar = new barcodecs(); BProduct objprod = new BProduct() { ProductName = model.ProductName, Description = model.Description, ImageUrl = model.ImageUrl, BarCodeID = model.BarCodeID, Barcode = objbar.generateBarcode(), BarcodeImage = objbar.getBarcodeImage(objbar.generateBarcode(), model.ProductName) }; BProduct.InsertOnSubmit(objprod); SubmitChanges(); return RedirectToAction("Mixxim_ICT", "Home"); } private void SubmitChanges() { throw new NotImplementedException(); } static void Main(string[] args) { try { FutureFeature(); } catch (NotImplementedException notImp) { Console.WriteLine(notImp.Message); } } static void FutureFeature() { // Not developed yet. throw new NotImplementedException(); } public ActionResult BarCode() SqlConnection con = new SqlConnection("Data Source=-------\\SQLEXPRESS;Initial Catalog=storage;Integrated Security=sspi"); string query = "select * From Barcode"; DataTable dt = new DataTable(); con.Open(); SqlDataAdapter sda = new SqlDataAdapter(query, con); sda.Fill(dt); con.Close(); IList model = new List(); for (int i = 0; i < dt.Rows.Count; i++) { var p = dt.Rows[i]["BarCodeImage"]; model.Add(new BProduct() { ProductName = dt.Rows[i]["ProductName"].ToString(), Description = dt.Rows[i]["Description"].ToString(), Barcode = dt.Rows[i]["Barcode1"].ToString(), ImageUrl = dt.Rows[i]["BarCodeImage"] != null ? "data:image/jpg;base64," + Convert.ToBase64String((byte[])dt.Rows[i]["BarCodeImage"]) : "" } ); } return View(model); } } }解决方案"when i run the project and click create
i get this:An exception of type 'System.NotImplementedException' occurred in ITCompany.dll but was not handled in user code"
Look at your code:
static void Main(string[] args) { try { FutureFeature(); } catch (NotImplementedException notImp) { Console.WriteLine(notImp.Message); } } static void FutureFeature() { // Not developed yet. throw new NotImplementedException(); }
All it will ever do is throw a NotImplementedException - because that is all you have told it to do!
