当 SQL Server 表列数据类型为时，我可以保存这些信息，nvarchar(MAX)但我需要使用其他数据类型保存数据。

这是我的数据库，我需要将数据保存到表中，但我不能使用我的代码来做，但我可以使用nvarchar(MAX)数据格式保存到数据库中

数据库映像

    protected void btnSaave_Click(object sender, EventArgs e)
    {
        int rowIndex = 0;
        StringCollection sc = new StringCollection();
        if (ViewState["CurrentData"] != null)
        {
            DataTable dtCurrentTable = (DataTable)ViewState["CurrentData"];
            DataRow drCurrentRow = null;
            if (dtCurrentTable.Rows.Count > 0)
            {
                for (int i = 1; i <= dtCurrentTable.Rows.Count; i++)
                {
                    var dtDealerCode = txtIDealerCode.Text;
                    var dtInvoiceNo = txtInvoiceNumber.Text;
                    var dtInvoiceDate = txtInvoiceDate.Text;
                    var dtItemIdentityCode = (Label)GridView1.Rows[rowIndex].Cells[1].FindControl("ItemCode");
                    var dtPurchasingPrice = (Label)GridView1.Rows[rowIndex].Cells[3].FindControl("UnitPrice");
                    var dtDiscountRate = txtDiscount.Text;
                    var dtDiscount = txtProductDiscount.Text;
                    var dtIssueMode = ddlIssueMode.SelectedValue;
                    var dtQty = (Label)GridView1.Rows[rowIndex].Cells[6].FindControl("Quantity");
                    var dtTotal = (Label)GridView1.FooterRow.FindControl("GetTotal");
                    var dtExpireDate = (Label)GridView1.Rows[rowIndex].Cells[5].FindControl("ExpiaryDate");
                    var dtBatchNumber = (Label)GridView1.Rows[rowIndex].Cells[4].FindControl("Batch");
                    var dtUploadedStatus = txtInvoiceDate.Text;
                    var dtInsertedDate = "1";
                    var dtUploadedDate = txtInvoiceDate.Text;
                    var dtForce = txtForce.Text;
                    var dtPrinciple = txtPrinciple.Text;
                    var NewTotal = (Label)GridView1.FooterRow.FindControl("GetQuantity");
                    // (Label)GridView1.Rows[rowIndex].Cells[7].FindControl("Total");
                    //(Label)GridView1.Rows[rowIndex].Cells[2].FindControl("Product")
                    sc.Add(dtDealerCode + "," + dtInvoiceNo + "," + dtInvoiceDate + "," + dtItemIdentityCode.Text + "," + dtPurchasingPrice.Text + "," + dtDiscountRate + "," + dtDiscount + "," + dtIssueMode + "," + dtQty.Text + "," + dtTotal.Text + "," + dtExpireDate + "," + dtBatchNumber.Text + "," + dtUploadedStatus + "," + dtInsertedDate + "," + dtUploadedDate + "," + dtForce + "," + dtPrinciple + "," + dtPrinciple + "," + NewTotal.Text);
                    rowIndex++;
                }

                InsertRec(sc);
            }
        }
    }

我正在使用这部分保存到数据库中，

我需要将数据保存到表中，但我不能使用我的代码来做，但我可以使用nvarchar(MAX)数据格式保存到数据库中

private void InsertRec(StringCollection sc)
    {
        var conn = new SqlConnection(GetConnectionString());
        var sb = new StringBuilder(string.Empty);
        var splitItems = (string[])null;
        foreach (string item in sc)
        {
            const string sqlStatement =
                "INSERT INTO DEL_PurchasesLines1 (DealerCode,InvoiceNo,InvoiceDate,ItemIdentityCode,PurchasingPrice,DiscountRate,Discount,IssueMode,Qty,Total,ExpireDate,BatchNumber,UploadedStatus,InsertedDate,UploadedDate,Force,Principle,NewTotal) VALUES";

            if (item.Contains(","))
            {
                splitItems = item.Split(",".ToCharArray());
                sb.AppendFormat("{0}('{1}','{2}','{3}','{4}','{5}','{6}','{7}','{8}','{9}','{10}','{11}','{12}','{13}','{14}','{15}','{16}','{17}','{18}'); ", sqlStatement, splitItems[0], splitItems[1], splitItems[2], splitItems[3], splitItems[4], splitItems[5], splitItems[6], splitItems[7], splitItems[8], splitItems[9], splitItems[10], splitItems[11], splitItems[12], splitItems[13], splitItems[14], splitItems[15], splitItems[16], splitItems[17]);
            }
        }

        try
        {
            conn.Open();
            SqlCommand cmd = new SqlCommand(sb.ToString(), conn) { CommandType = CommandType.Text };
            cmd.ExecuteNonQuery();

            Page.ClientScript.RegisterClientScriptBlock(typeof(Page), "Script", "alert('Records Successfuly Saved!');", true);

        }
        catch (System.Data.SqlClient.SqlException ex)
        {
            string msg = "Insert Error:";
            msg += ex.Message;
            throw new Exception(msg);
        }
        finally
        {
            conn.Close();
        }
    }

将您的 nvarchar 值传递给此方法..

public static DateTime DateParse(string date)
        {
            date = date.Trim();
            if (!string.IsNullOrEmpty(date))
            return DateTime.Parse(date, new System.Globalization.CultureInfo("en-GB"));
            return new DateTime();
        }

您可以在从中获取数据时应用 convert.ToDateTime Datatable，但是我认为您不需要执行所有这些拆分函数来获取Insert查询的值，您可以直接将stringCollection sc字符串应用于插入查询中的值字段，无需转换需要在这里完成。

sc.Add(dtDealerCode + "," + dtInvoiceNo + "," + Convert.ToDateTime(dtInvoiceDate) + "," + dtItemIdentityCode.Text + "," + dtPurchasingPrice.Text + "," + dtDiscountRate + "," + dtDiscount + "," + Convert.ToDateTime(dtIssueMode) + "," + dtQty.Text + "," + dtTotal.Text + "," + Convert.ToDateTime(dtExpireDate) + "," + dtBatchNumber.Text + "," + dtUploadedStatus + "," + dtInsertedDate + "," + Convert.ToDateTime(dtUploadedDate) + "," + dtForce + "," + dtPrinciple + "," + dtPrinciple + "," + NewTotal.Text);

const string sqlStatement =
                "INSERT INTO DEL_PurchasesLines1 (DealerCode,InvoiceNo,InvoiceDate,ItemIdentityCode,PurchasingPrice,DiscountRate,Discount,IssueMode,Qty,Total,ExpireDate,BatchNumber,UploadedStatus,InsertedDate,UploadedDate,Force,Principle,NewTotal) VALUES"(yourstringCollection);

这里还有一件事是您只获取控件而不是它们的值来从控件使用中获取值.Text。

 var dtExpireDate = (Label)GridView1.Rows[rowIndex].Cells[5].FindControl("ExpiaryDate").text;
