Here's my code I'm trying to replace an image from one folder with another image in another folder while conserving his file name. I'm retrieving the content of the folder using dataGridView I'm loading the image from the cell selected directly to a picturebox I'm using: File.Copy(Source, Destination,true); To copy my file, I made sure to dispose of EVERYTHING so it's not being used by the process.

My full project (commented):

private void Form1_Load(object sender, EventArgs e)
{
    //Get content of the DESTINATION files on a specific folder and put it into a dataGridView1

    string[] files = Directory.GetFiles(@Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)   "\\Black Desert\\FaceTexture", "*", SearchOption.TopDirectoryOnly);
    DataTable table = new DataTable();
    table.Columns.Add("File Name");
    for (int i = 0; i < files.Length; i  )
    {
        FileInfo file = new FileInfo(files[i]);
        table.Rows.Add(file.Name);

    }
    dataGridView1.DataSource = table;

    //Get content of the SOURCE files on a specific folder and put it into a dataGridView2

    string[] files2 = Directory.GetFiles(@"Face Texture", "*");
    DataTable table2 = new DataTable();
    table2.Columns.Add("File Name");
    for (int i = 0; i < files2.Length; i  )
    {
        FileInfo file = new FileInfo(files2[i]);
        table2.Rows.Add(file.Name);

    }
    dataGridView2.DataSource = table2;
}

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
    try
    {
        string[] sizes = { "B", "KB", "MB", "GB", "TB" };
        double len = new FileInfo(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)   "\\Black Desert\\FaceTexture\\"   dataGridView1.SelectedCells[0].Value.ToString()).Length;
        int order = 0;
        while (len >= 1024 && order < sizes.Length - 1)
        {
            order  ;
            len = len / 1024;
        }

        string result = String.Format("{0:0.##} {1}", len, sizes[order]);

        //We get the picturebox to show which file we selected in the cell (datagridview1)
        pictureBox1.Image = Image.FromFile(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)   "\\Black Desert\\FaceTexture\\"   dataGridView1.SelectedCells[0].Value.ToString());

        LblFileSize1.Text = result;

CodePudding user response：

You want to dispose of the image object and not the PictureBox object.

Therefore pictureBox.Image.Dispose() will solve the issue.

So PictureBox has image property class that has a Dispose() method
