You have some CSV files stored in a folder on your server and you want to let the user download each separately. You will need a ASP.NET placeholder (ID="Downloads") on your UI.
private void CheckForDownloadFiles(string filePath)
{
DirectoryInfo d = new DirectoryInfo(filePath);
FileInfo[] Files = d.GetFiles("*.csv"); //Getting CSV files
Downloads.Controls.Clear();
string str = ""; int i = 0;
foreach (FileInfo file in Files)
{
str = str + ", " + file.Name;
i++;
CreateLinkButtonAndLabel(file.Name,i, filePath);
}
}
private void CreateLinkButtonAndLabel(string fileName, int count, string filePath)
{
Downloads.Controls.Add(new LiteralControl("<br />"));
LinkButton newDownload = new LinkButton();
newDownload.ID = "DownloadBtn"+count;
newDownload.CommandArgument = filePath+fileName;
newDownload.Click += new EventHandler(DownloadCSV);
newDownload.CssClass += "btn btn-success btn-xs";
newDownload.Text = "<img src='../Images/icons/csv-file.gif' alt='Download CSV File' /> Download CSV";
Downloads.Controls.Add(newDownload);
Label label = new Label();
label.ID = "DownloadLabel" + count;
label.Text = " "+fileName+" ";
Downloads.Controls.Add(label);
}
protected void DownloadCSV(object sender, EventArgs e)
{
LinkButton btn = (LinkButton)sender;
string fullFilePath = btn.CommandArgument;
if(fileName.Contains("csv"))
Response.Redirect(fullFilePath);
}
This will create a button and display the name of your file next to it:
private void CheckForDownloadFiles(string filePath)
{
DirectoryInfo d = new DirectoryInfo(filePath);
FileInfo[] Files = d.GetFiles("*.csv"); //Getting CSV files
Downloads.Controls.Clear();
string str = ""; int i = 0;
foreach (FileInfo file in Files)
{
str = str + ", " + file.Name;
i++;
CreateLinkButtonAndLabel(file.Name,i, filePath);
}
}
private void CreateLinkButtonAndLabel(string fileName, int count, string filePath)
{
Downloads.Controls.Add(new LiteralControl("<br />"));
LinkButton newDownload = new LinkButton();
newDownload.ID = "DownloadBtn"+count;
newDownload.CommandArgument = filePath+fileName;
newDownload.Click += new EventHandler(DownloadCSV);
newDownload.CssClass += "btn btn-success btn-xs";
newDownload.Text = "<img src='../Images/icons/csv-file.gif' alt='Download CSV File' /> Download CSV";
Downloads.Controls.Add(newDownload);
Label label = new Label();
label.ID = "DownloadLabel" + count;
label.Text = " "+fileName+" ";
Downloads.Controls.Add(label);
}
protected void DownloadCSV(object sender, EventArgs e)
{
LinkButton btn = (LinkButton)sender;
string fullFilePath = btn.CommandArgument;
if(fileName.Contains("csv"))
Response.Redirect(fullFilePath);

This will create a button and display the name of your file next to it:
