C# - Get Files from Folder / Directory & bind to Asp.net Gridview in C#, VB.NET

Here I will explain how to get files from folder or directory and bind to Gridview in asp.net using C#, VB.NET.

Description:

In previous articles I explained create zip files in asp.net, Delete files from uploaded folder in asp.net, create/delete directory in asp.net, Joins in SQL Serverand many articles relating to Gridview, SQL ,jQuery,asp.net, C#,VB.NET. Now I will explain how to get files from folder and bind to Gridview in asp.net using C#, VB.NET.

To display files from folder in Gridview we need to write the code like as shown below

C# Code

string[] filesPath = Directory.GetFiles(Server.MapPath("~/SampleFiles/"));

List<ListItem> files = new List<ListItem>();

foreach (string path in filesPath)

{

files.Add(new ListItem(Path.GetFileName(path)));

}

gvDetails.DataSource = files;

gvDetails.DataBind();

VB Code

Dim filesPath As String() = Directory.GetFiles(Server.MapPath("~/SampleFiles/"))

Dim files As New List(Of ListItem)()

For Each path__1 As String In filesPath

files.Add(New ListItem(Path.GetFileName(path__1)))

gvDetails.DataSource = files

gvDetails.DataBind()

If you want to check it in complete example write the following code

<head>

<title>Get files from folder & bind to gridview in c#.net</title>

</head>

<body>

<div>

<asp:Button ID="btnGetFiles" Text="Get Files From Folder" runat="server" onclick="btnGetFiles_Click" />

<asp:GridView ID="gvDetails" CellPadding="5" runat="server" AutoGenerateColumns="false">

<asp:BoundField DataField="Text" HeaderText="FileName" />

</Columns>

</asp:GridView>

</div>

</form>

</body>

</html>

Now in code behind add the following namespaces

C# Code

using System;

using System.Collections.Generic;

using System.IO;

using System.Web.UI.WebControls;

Once you add namespaces write the following code in code behind

// insert files in folder

protected void btnGetFiles_Click(object sender, EventArgs e)

{

BindGridview();

}

// Bind Data to Gridview

protected void BindGridview()

{

string[] filesPath = Directory.GetFiles(Server.MapPath("~/SampleFiles/"));

List<ListItem> files = new List<ListItem>();

foreach (string path in filesPath)

{

files.Add(new ListItem(Path.GetFileName(path)));

}

gvDetails.DataSource = files;

gvDetails.DataBind();

}

VB.NET Code

Imports System.Collections.Generic

Imports System.IO

Imports System.Web.UI.WebControls

Partial Class VBCode1

Inherits System.Web.UI.Page

' 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 filesPath As String() = Directory.GetFiles(Server.MapPath("~/SampleFiles/"))

Dim files As New List(Of ListItem)()

For Each path__1 As String In filesPath

files.Add(New ListItem(Path.GetFileName(path__1)))

gvDetails.DataSource = files

gvDetails.DataBind()

End Sub

End Class
