Introduction:
Here I will explain how to get all files from folder and subfolders in C# and display or bind to Gridview in asp.net using C#, VB.NET or C# Get All Files from Folder and Subfolders and Display it in Gridview in asp.net.
Description:
In previous articles I explained Download files from gridview with link button in asp.net, Upload images to folder and display it in gridview in asp.net, create zip files in asp.net, Delete files from uploaded folder in asp.net, create/delete directory in asp.net, Joins in SQL Server and many articles relating to Gridview, SQL , jQuery , asp.net, C#, VB.NET. Now I will explain how to get all files from folder and subfolders and bind to Gridview in asp.net using C#, VB.NET.

To display all files from folder and subfolders in Gridview we need to write the code like as shown below
C# Code
// Bind Data to Gridview
protected void BindGridview()
{
string strpath = @"E:\Internet Tips\";
string[] folders = Directory.GetFiles(strpath, "*", SearchOption.AllDirectories);
gvDetails.DataSource = folders;
gvDetails.DataBind();
}
VB Code
' Bind Data to Gridview
Protected Sub BindGridview()
Dim strpath As String = "E:\Internet Tips\"
Dim folders As String() = Directory.GetFiles(strpath, "*", SearchOption.AllDirectories)
gvDetails.DataSource = folders
gvDetails.DataBind()
End Sub
If you want to check it in complete example write the following code
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Get files from folder & subfolder & display it in gridview in c#.net</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="btnGetFiles" Text="Get Files From Folder & Sub Folders" runat="server" onclick="btnGetFiles_Click" />
<asp:GridView ID="gvDetails" CellPadding="5" runat="server">
<HeaderStyle BackColor="#df5015" Font-Bold="true" ForeColor="White" />
</asp:GridView>
</div>
</form>
</body>
</html>
Now in code behind add the following namespaces
C# Code
using System;
using System.IO;
Once you add namespaces write the following code in code behind
// Get files in folder
protected void btnGetFiles_Click(object sender, EventArgs e)
{
BindGridview();
}
// Bind Data to Gridview
protected void BindGridview()
{
string strpath = @"E:\Internet Tips\";
string[] folders = Directory.GetFiles(strpath, "*", SearchOption.AllDirectories);
gvDetails.DataSource = folders;
gvDetails.DataBind();
}
VB.NET Code
Imports System.IO
Partial Class VBCode
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
End Sub
' insert files in folder
Protected Sub btnGetFiles_Click(ByVal sender As Object, ByVal e As EventArgs)
BindGridview()
End Sub
' Bind Data to Gridview
Protected Sub BindGridview()
Dim strpath As String = "E:\Internet Tips\"
Dim folders As String() = Directory.GetFiles(strpath, "*", SearchOption.AllDirectories)
gvDetails.DataSource = folders
gvDetails.DataBind()
End Sub
End Class
