<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="2" 
      ForeColor="#333333" GridLines="None" AllowPaging="True"> 
      <Columns> 
       <asp:TemplateField>

         <asp:LinkButton ID="lnkdownload" runat="server" Text="Download" CommandName="Download" 
          CommandArgument='<%#Eval("FullName") +";" + Eval("Name") %>'></asp:LinkButton> 
        </ItemTemplate> 
       </asp:TemplateField> 
       <asp:BoundField DataField="Name" HeaderText="File Name" /> 
       <asp:BoundField DataField="Length" HeaderText="Size (Bytes)" /> 
      </Columns>

Voici le code converti en C# en utilisant un VB.NET to C# Converter:

private void BindGrid() 
{ 
    string DataDirectory = "~/Uploads"; 
    FileInfo[] files = new DirectoryInfo(Server.MapPath(DataDirectory)).GetFiles; 
    GridView1.DataSource = files; 
    GridView1.DataBind(); 
} 

protected void Page_Load(object sender, System.EventArgs e) 
{ 
    if (!IsPostBack) { 
     BindGrid(); 
    } 
} 

private void Downloadfile(string fileName, string FullFilePath) 
{ 
    Response.AddHeader("Content-Disposition", "attachment; filename=" + fileName); 
    Response.TransmitFile(FullFilePath); 
    Response.End(); 
} 

protected void GridView1_RowCommand(object sender, 
    System.Web.UI.WebControls.GridViewCommandEventArgs e) 
{ 
    if (e.CommandName == "Download") { 
     string[] fileInfo = e.CommandArgument.ToString().Split(";"); 
     string FileName = fileInfo[1]; 
     string FullPath = fileInfo[0]; 
     Downloadfile(FileName, FullPath); 
    } 
} 

protected void GridView1_PageIndexChanging(object sender, 
    System.Web.UI.WebControls.GridViewPageEventArgs e) 
{ 
    GridView1.PageIndex = e.NewPageIndex; 
    BindGrid(); 
}

C# ne pas le mot-clé "poignées" comme VB.Net fait, il ressemble à votre GridView est pas correctement câblé au gestionnaire nécessaire. Essayez d'ajouter le paramètre suivant à votre balise GridView:

OnRowCommand="GridView1_RowCommand" 

Notez que vous aurez besoin de faire la même chose pour votre index de page événement qui change aussi.
