Wie bereits, wenn Daten in der Datenbank zu überprüfen, in C# existieren

Question

private int AddRecordCategory() 
{ 
     AdminAllCategory aAdminAllCategory = new AdminAllCategory(); 
     AdminAllCategoryBLL allCategoryBLL = new AdminAllCategoryBLL(); 

     int Action = 0; 

     try 
     { 
      if (CategoryID > 0) 
      { 
       aAdminAllCategory.CategoryId = Convert.ToInt32(CategoryIdtxt.Text); 
      } 
      else 
      { 
       //CategoryGateway objCategoryGateway = new CategoryGateway(); 
       string columnName = "CategoryID"; 
       string tableName = "Deal.Category"; 
       aAdminAllCategory.CategoryId = allCategoryBLL.MaxId(columnName, tableName) + 1; 
      } 

      aAdminAllCategory.Category = BanglaCategory.Text; 
      aAdminAllCategory.CategoryEng = EnglishCategory.Text; 
      aAdminAllCategory.IsActive = Convert.ToInt32(IsActive.Text); 
      aAdminAllCategory.IsHit = Convert.ToInt32(HitDropDown.Text); 
      aAdminAllCategory.OrderBy = Convert.ToInt32(OrderBy.Text); 

      if (Hit.Text != "") 
      { 
       aAdminAllCategory.hit = Convert.ToInt32(Hit.Text); 
      } 
      else 
      { 
       aAdminAllCategory.hit = 0; 
      } 

      aAdminAllCategory.MetaKeyword = metaKeyWord.InnerText; 
      aAdminAllCategory.MetaDescription = MetaDescription.InnerText; 
      aAdminAllCategory.VisibleInDevice = Convert.ToInt32(IsVisible.SelectedValue); 
      aAdminAllCategory.AppColorCode = AppColorCode.Text; 

      aAdminAllCategory.CategoryTitleBng = BngPageTitle.Text; 
      aAdminAllCategory.CategoryTitleEng = EngPageTitle.Text; 

      Action = allCategoryBLL.InsertCategory(aAdminAllCategory); 
     } 
     catch (Exception ex) 
     { 
      lblSystemMessage.Text = "Warning!!Contact With IT"; 
     } 

     return Action; 
} 

Hier mag ich diese Attribute in der Datenbank speichern, aber möchte sehen, ob CategoryTitleEng und CategoryTitleBng Eigenschaften in der Datenbank gespeichert werden, bevor diese Spalte gespeichert werden. Dann zeigt das eine Nachricht wie:

Diese Eigenschaften sind bereits vorhanden.

Das Gateway und die gespeicherte Prozedur sind unten .....

public int AddRecord_Category(AdminAllCategory aAdminAllCategory) 
{ 
    int intActionResult = 0; 
    int isActive = 1; 
    //int isDeleted = 0; 

    try 
    { 
     OpenConnection(); 
     ArrayList arlSqlParameters = new ArrayList(); 
     arlSqlParameters.Add(new SqlParameter("@CategoryID", aAdminAllCategory.CategoryId)); 
     arlSqlParameters.Add(new SqlParameter("@Category", aAdminAllCategory.Category)); 
     arlSqlParameters.Add(new SqlParameter("@IsHit", aAdminAllCategory.IsHit)); 
     arlSqlParameters.Add(new SqlParameter("@IsActive", aAdminAllCategory.IsActive)); 
     arlSqlParameters.Add(new SqlParameter("@OrderBy", aAdminAllCategory.OrderBy)); 
     arlSqlParameters.Add(new SqlParameter("@CategoryEng", aAdminAllCategory.CategoryEng)); 
     arlSqlParameters.Add(new SqlParameter("@MetaKeyword", aAdminAllCategory.MetaKeyword)); 
     arlSqlParameters.Add(new SqlParameter("@MetaDescription", aAdminAllCategory.MetaDescription)); 
     arlSqlParameters.Add(new SqlParameter("@VisibleInDevice", aAdminAllCategory.VisibleInDevice));

     arlSqlParameters.Add(new SqlParameter("@CategoryTitleEng",aAdminAllCategory.CategoryTitleEng)); 
     arlSqlParameters.Add(new SqlParameter("@CategoryTitleBng", aAdminAllCategory.CategoryTitleBng)); 

      intActionResult = this.ExecuteActionQuery("Deal.USP_AddDealsCategory", arlSqlParameters); 

    } 
    catch (Exception ex) 
    { 
    } 
    finally 
    { 
     CloseConnection(); 
    } 

    return intActionResult; 
}

END 

Answer 1

Sie haben die Eigenschaft @CategoryTitleBng zweimal auf Ihre Parameterliste hinzugefügt gezeigt. das ist, warum ist es den Fehler geben nur einmal

arlSqlParameters.Add(new SqlParameter("@CategoryTitleBng", aAdminAllCategory.CategoryTitleBng));
