如何使用Windows窗体在datagridview中显示计数

Question

在我的应用程序中，我显示消息，如果文件上传成功，同时我显示的消息不会在消息框中上传。

问题是我需要在消息框中每次单击确定按钮时，每当消息occours。假设如果没有插入40个文件，我需要点击OK按钮40次。我需要显示在datagridview中插入和未插入的文件。我怎样才能做到这一点。

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); 
}

我认为你必须做在你上传文件循环，你必须在这个循环中加入

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

当循环结束试图表明消息框

要显示在datagridview中的图像，你必须插入DataGridViewImageColumn类型的列，然后你可以在里面显示图像。

 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; 
      } 
     }
