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;
}

在这里，我想将这些属性保存在数据库中，但希望在保存这些列之前查看是否将CategoryTitleEng和CategoryTitleBng属性保存在数据库中。然后，这将显示如下消息：

这些属性已经存在。

网关和存储过程如下所示.....

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("@AppColorCode", aAdminAllCategory.AppColorCode));
        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

您已将属性@CategoryTitleBng两次添加到参数列表中。这就是为什么它会给出错误这应该只是一次

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

如何在c＃中检查数据库中是否已存在数据
