Questionexportar datos de sql server a archivo .csv con C# asp.net Pin
Member 1556240011-Mar-22 9:08
Member 1556240011-Mar-22 9:08 
Hello group, a question please. The data from my databases all come out in a single string per row in the .csv file, how can I print it in a cell per field in the .csv file? I attach images and code for more clarity with the problem. Thanks


<pre lang="C#">
public partial class CS : System.Web.UI.Page {
protected void ExportCSV(object sender, EventArgs e)
{
string constr = ConfigurationManager.ConnectionStrings["PRUEBASConnectionString"].ConnectionString;
using (SqlConnection con = new SqlConnection(constr))
{
using (SqlCommand cmd = new SqlCommand("SELECT * FROM Customers"))
{
using (SqlDataAdapter sda = new SqlDataAdapter())
{
cmd.Connection = con;
sda.SelectCommand = cmd;
using (DataTable dt = new DataTable())
{
sda.Fill(dt);

//Build the CSV file data as a Comma separated string.
string csv = string.Empty;

foreach (DataColumn column in dt.Columns)
{
//Add the Header row for CSV file.
csv += column.ColumnName + ',';
}

//Add new line.
csv += "\r\n";

foreach (DataRow row in dt.Rows)
{
foreach (DataColumn column in dt.Columns)
{
//Add the Data rows.
csv += row[column.ColumnName].ToString().Replace(",", ";") + ',';
}

//Add new line.
csv += "\r\n";
}

//Download the CSV file.
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment;filename=SqlExport.csv");
Response.Charset = "";
Response.ContentType = "application/text";
Response.Output.Write(csv);
Response.Flush();
Response.End();
}
}
}
}
} }
