I want to get image from the file..I m able to do it....But mine code do not close the file,after getting the image,I want to close the file.Cz after getting the image,I want to delete that file.....on Deleteing error is dere file is user by another process...

VB.NET Syntax (Toggle Plain Text)
Public Sub GetImagesContent(ByVal sFileName As String)
        Try
            Dim sExtension As String
            Dim img As System.Drawing.Image
 
            sExtension = System.IO.Path.GetExtension(sFileName)
            If Trim(sExtension) = ".bmp" Or _
                Trim(sExtension) = ".jpg" Or _
                Trim(sExtension) = ".jpeg" Or _
                Trim(sExtension) = ".gif" Or _
                Trim(sExtension) = ".png" Then
                img = Image.FromFile(sFileName)
                ImgThumbNailView.Images.Add(img)
           End if
Public Sub GetImagesContent(ByVal sFileName As String)
        Try
            Dim sExtension As String
            Dim img As System.Drawing.Image

            sExtension = System.IO.Path.GetExtension(sFileName)
            If Trim(sExtension) = ".bmp" Or _
                Trim(sExtension) = ".jpg" Or _
                Trim(sExtension) = ".jpeg" Or _
                Trim(sExtension) = ".gif" Or _
                Trim(sExtension) = ".png" Then
                img = Image.FromFile(sFileName)
                ImgThumbNailView.Images.Add(img)
           End if

Re: Get Image From file

Use FileStream class:

VB.NET Syntax (Toggle Plain Text)
Public Class Form1
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Try
            Dim img As Image
            Dim sFileName As String = "D:\Documents and Settings\Mansi\Desktop\Winter.jpg"
            Dim fs as new System.IO.FileStream(sFileName,System.IO.FileMode.Open)
            img = Image.FromStream(fs)
            fs.close()
            ImageList1.Images.Add(img)
            PictureBox1.Image = ImageList1.Images.Item(0)
            img.Dispose()
            System.IO.File.Delete(sFileName)
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
    End Sub
End Class
Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Try
            Dim img As Image
            Dim sFileName As String = "D:\Documents and Settings\Mansi\Desktop\Winter.jpg"
            Dim fs as new System.IO.FileStream(sFileName,System.IO.FileMode.Open)
            img = Image.FromStream(fs)
            fs.close()
            ImageList1.Images.Add(img)
            PictureBox1.Image = ImageList1.Images.Item(0)
            img.Dispose()
            System.IO.File.Delete(sFileName)
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
    End Sub
End Class
