public DataTable InsertItemDetails(FeedRetailPL objFeedRetPL)
{
    DataTable GetListID = new DataTable();
    try
    {
        SqlParameter[] arParams = new SqlParameter[4];

        arParams[0] = new SqlParameter("@Date", typeof(DateTime));
        arParams[0].Value = objFeedRetPL.requestdate;

    }
    catch (Exception ex)
    {
        string dir = @"C:\Error.txt";  // folder location
        if (!Directory.Exists(dir))
        {
            Directory.CreateDirectory(dir);
            File.AppendAllText(Server.MapPath("~/Error.txt"), "Message :" + ex.Message + "<br/>" + Environment.NewLine + "StackTrace :" + ex.StackTrace +
       "" + Environment.NewLine + "Date :" + DateTime.Now.ToString());
            string New = Environment.NewLine + "-----------------------------------------------------------------------------" + Environment.NewLine;
            File.AppendAllText(Server.MapPath("~/Error.txt"), New);
        }
    }
}

在这里,我想在"C:\"中保存一个异常..我正在尝试在DAL ...如何在C驱动器中保存异常Error.txt

Create PROCEDURE [dbo].[K_RT_FixedAsset]
@fromdate datetime,
@todate datetime
AS
BEGIN

SET NOCOUNT ON;

 select convert(varchar,FT.date,103)as date, MR.branch as frombranch,PD.productname as product,FT.vehicleno,FT.dcno,FT.tobranch 
from K_RT_FixedAssetTransfer FT
inner join K_RT_MasterRetailStores MR on MR.sno = FT.frombranch 
inner join K_RT_ProductDetails PD on PD.sno=FT.product
inner join K_RT_MasterRetailStores MR on MR.sno = FT.tobranch 
where FT.date between @fromdate and  @todate


END

如何使用foreach循环方法替换为clear()..请告诉我..任何一个......是否有可能编写foreach循环...请告诉我

protected void btnbatch_Click(object sender, EventArgs e)
{       
    Button btnactual= sender as Button;
