使用foreach将gridview数据插入sql数据库答案

【问题标题】：Using foreach for insert gridview data into sql database使用foreach将gridview数据插入sql数据库

【问题描述】：

我有一个客户端 gridview 数据，我想将 gridview 数据插入 sql 数据库。起初我将数据从 excel 导入到 gridview，现在我想将其插入到 sql 数据库中。

我使用 foreach 循环一一插入记录。但 foreach 循环只选择第一条记录，我不能增加行索引。我怎样才能做到这一点？并选择其他记录？

protected void btnInsertIntoDatabase_Click(object sender, EventArgs e)
    {
    A:
        string Name = string.Empty;
        string CarType = string.Empty;
        string TechnicalNo = string.Empty;
        string ProductionDate = string.Empty;
        string EngaineType = string.Empty;
        string NoInStock = string.Empty;
        string NoForCar = string.Empty;
        string Price = string.Empty;
        string Image = string.Empty;
        string Desc = string.Empty;
        string PartType = string.Empty;
        string Level = string.Empty;
        string Unit = string.Empty;
        string Ratio = string.Empty;
        string Dirham = string.Empty;
        string ExtraMoney = string.Empty;

        int GVCount = GridView1.Rows.Count;

        foreach (GridViewRow GVRow in GridView1.Rows)
        {
            Name = GVRow.Cells[1].Text;
            CarType = GVRow.Cells[2].Text;
            TechnicalNo = GVRow.Cells[3].Text;
            ProductionDate = GVRow.Cells[4].Text;
            EngaineType = GVRow.Cells[5].Text;
            NoInStock = GVRow.Cells[6].Text;
            NoForCar = GVRow.Cells[7].Text;
            Price = GVRow.Cells[8].Text;
            Image = GVRow.Cells[9].Text;
            Desc = GVRow.Cells[10].Text;
            PartType = GVRow.Cells[11].Text;
            Level = GVRow.Cells[12].Text;
            Unit = GVRow.Cells[13].Text;
            Ratio = GVRow.Cells[14].Text;
            Dirham = GVRow.Cells[15].Text;
            ExtraMoney = GVRow.Cells[16].Text;
            break;
        }

        SqlConnection scn = new SqlConnection(clspublic.GetConnectionString());
        SqlCommand scm = new SqlCommand();
        scm.Connection = scn;
        scm.CommandText = @"INSERT INTO tblProduct

【问题讨论】：

因为 break 你的代码不起作用检查我为你粘贴的代码....如果你像这样使用 break 你每次只会得到第一条记录

标签： c# asp.net gridview

【解决方案1】：

它取得第一条记录只是因为你的 foreach 循环中写了break...

以下是适合您的代码

    foreach (GridViewRow GVRow in GridView1.Rows)
    {
        Name = GVRow.Cells[1].Text;
        CarType = GVRow.Cells[2].Text;
        TechnicalNo = GVRow.Cells[3].Text;
        ProductionDate = GVRow.Cells[4].Text;
        EngaineType = GVRow.Cells[5].Text;
        NoInStock = GVRow.Cells[6].Text;
        NoForCar = GVRow.Cells[7].Text;
        Price = GVRow.Cells[8].Text;
        Image = GVRow.Cells[9].Text;
        Desc = GVRow.Cells[10].Text;
        PartType = GVRow.Cells[11].Text;
        Level = GVRow.Cells[12].Text;
        Unit = GVRow.Cells[13].Text;
        Ratio = GVRow.Cells[14].Text;
        Dirham = GVRow.Cells[15].Text;
        ExtraMoney = GVRow.Cells[16].Text;


    SqlConnection scn = new SqlConnection(clspublic.GetConnectionString());
 using(con)
 {  
    SqlCommand scm = new SqlCommand();
    scm.Connection = scn;
    scm.CommandText = @"INSERT INTO tblProduct
                      (fName, fxCarType, fProductionDate, fEngineType, fNoinStock, fNoforCar, fPrice,fRatio,fDirham,fExtraMoney, fImage, fDesc, fxPartType, fxLevel,fUnitType,fTechnicalNo)
           VALUES     (@fName,@fxCarType,@fProductionDate,@fEngineType,@fNoinStock,@fNoforCar,@fPrice,@fRatio,@fDirham,@fExtraMoney,@fImage,@fDesc,@fxPartType,@fxLevel,@fUnitType,@fTechnicalNo)";

    scm.Parameters.AddWithValue("@fName", Name.ToString());
    scm.Parameters.AddWithValue("@fxCarType", CarType.ToString());
    scm.Parameters.AddWithValue("@fTechnicalNo", TechnicalNo.ToString());
    scm.Parameters.AddWithValue("@fProductionDate", ProductionDate.ToString());
    scm.Parameters.AddWithValue("@fEngineType", EngaineType.ToString());

    scm.Parameters.AddWithValue("@fUnitType", Unit.ToString());
    scm.Parameters.AddWithValue("@fxLevel", Level.ToString());

   scm.ExecuteNonQuery();
 }

}

【讨论】：

是的，我打破了，因为我有超过 50 条记录，然后我的变量发生了变化。我想注册第一条记录，然后是第二条记录，然后 ....
你看到了吗，他使用了 Go To 语句？

【解决方案2】：

哇，Goto....

好吧，你在第一个记录后打破了你的 foreach。之后你从第一个开始你的 foreach ......

【解决方案4】：

这样试试，

如果所有控件都是标签

foreach (GridViewRow GVRow in GridView1.Rows)
    {

  Label lbl = (Label)GVRow.FindControl("labelID");

  string data=lbl.Text;

}

这个问题已经一年多以前回答了。为什么你再次发布几乎相同的代码，没有任何进一步的解释？
