Import Data to CSV File FROM DataTable

In th First step we will Clear the Response Object and then we'll attach a csv file with the Response Object. that will be popup once we'll write the Data into it and End the Response Object.

After Attaching the file we'll write the column Name into the CSV File. and then iterate for all the Records to write them into the CSV file.

"" is used to protect the Data if the data contain ',' (Comma) .

DataTable dtProducts=GetProductsFromDB();

string attachment = "attachment; filename=products.csv";

HttpContext.Current.Response.Clear();

HttpContext.Current.Response.ClearHeaders();

HttpContext.Current.Response.ClearContent();

HttpContext.Current.Response.AddHeader("content-disposition", attachment);

HttpContext.Current.Response.ContentType = "application/octet-stream";



//Write Column Names

string str = "ProductNo,Product,SKU,ProductType,Price";

HttpContext.Current.Response.Write(str);

HttpContext.Current.Response.Write(Environment.NewLine);

for(int i =0; i

{

  string strRowData="";

   for(int jColumns=0; jColumns

   {

    if(strRowData=="")

      strRowData='"'+dtProducts.Rows[jColumns].ToString()+'"';

     else

      {

           strRowData=","+'"'+dtProducts.Rows[jColumns].ToString()+'"';

      } 

   }

        HttpContext.Current.Response.Write(strRowData);

        HttpContext.Current.Response.Write(Environment.NewLine);

        strRowData="";

}

HttpContext.Current.Response.End();
