如何使用 Windows 窗体在 datagridview 中显示计数

Question

在我的应用程序中，如果文件上传成功，我会显示消息，同时我会在消息框中显示文件未上传的消息。

问题是每次出现消息时我都需要在消息框中单击确定按钮。假设如果没有插入 40 个文件，我需要单击确定按钮 40 次。我需要在datagridview中一次显示插入和未插入的文件。我该怎么做。

if (ErrorMessage == 0)
{
    Ffname += path + "-" + "Uploaded successfully" + "\n";
}
else
{
     NotInsFiles += path + " - " + "Not Inserted" + "\n";
}
lbluplodedfile.Text = TabNotIns;
if (Ffname != null || Ffname != "")
{
    MessageBox.Show(Ffname);
    lbluplodedfile.Text = Ffname;
}
else
{
    MessageBox.Show(NotInsFiles);
}

我认为您必须围绕上传文件进行循环，并且您必须在此循环中添加

if (ErrorMessage == 0)
{
    Ffname += path + "-" + "Uploaded successfully" + "\n";
}
else
{
     NotInsFiles += path + " - " + "Not Inserted" + "\n";
}

当循环结束时尝试显示消息框

要在 datagridview 中显示图像，您必须插入 DataGridViewImageColumn 类型的列，然后才能在其中显示图像。

        private void ImgToDataGridView()
        {
            /* List of path of img */
            List<string> pathImgUpload = new List<string>();
            List<string> pathNotInsert = new List<string>();

            /* Just for my test */
            pathImgUpload.Add("./abc.png");
            pathImgUpload.Add("./abc.png");
            pathImgUpload.Add("./abc.png");
            pathImgUpload.Add("./abc.png");

            pathNotInsert.Add("./abc.png");
            pathNotInsert.Add("./abc.png");
            pathNotInsert.Add("./abc.png");
            pathNotInsert.Add("./abc.png");
            pathNotInsert.Add("./abc.png");

            /* Creation of columns for the good and bad img */
            DataGridViewImageColumn colImgUpload = new DataGridViewImageColumn();
            DataGridViewImageColumn colImgNotInsert = new DataGridViewImageColumn();
            dataGridView1.Columns.Add(colImgUpload);
            dataGridView1.Columns.Add(colImgNotInsert);

            /* Max of size of pathImgUpload and pathNotInsert */
            var lineadd = pathImgUpload.Count > pathNotInsert.Count ? pathImgUpload.Count : pathNotInsert.Count;

            /* Create the good number of line (-1 because a first line is already in datagridview)*/
            for(int i = 0; i <lineadd - 1; i++)
            {
                dataGridView1.Rows.Add();
            }

            /* adding good img */
            for (int i = 0; i < pathImgUpload.Count(); i++)
            {
                string path = pathImgUpload[i];
                var img = new Bitmap(path);
                dataGridView1.Rows[i].Cells[0].Value = img;
            }

            /* adding bad img */
            for(int i = 0; i < pathNotInsert.Count();i++)
            {
                string path = pathNotInsert[i];
                var img = new Bitmap(path);
                dataGridView1.Rows[i].Cells[1].Value = img;
            }
        }
