DataGridView和PictureBox [英] DataGridView and PictureBox

问题描述

您好，我正在Microsoft Visual Studios 2008中的c#.net中开发一个图片查看器窗口应用程序.我被困在如何从gridview中获取选定的缩略图以显示在Picturebox中的问题上.

这是我使用的代码:

Hi, I am developing a picture viewer window application in c# .net in Microsoft visual studios 2008. I am stuck on how to get a selected thumbnail image from the gridview to be displayed in the Picturebox.

Here is the code i used:

private void dataViewImages_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
   string pic = dataViewImages.SelectedRows[0].ToString();
   pictureBox.Image = Image.FromFile(pic);
   tsbSave.Enabled = true;
   tsbRotate.Enabled = true;
   tsbCCRotate.Enabled = true;
}

我收到的错误消息是:

索引超出范围.必须为非负数并且小于集合的大小.
参数名称:索引.

-----------------------------
我知道它将与... SelectedRows [0]有关，但与此同时，我也不知道如何解决它.

The error message i am getting is:

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index.

-----------------------------
i know it will have to do with the ...SelectedRows[0] but at the same time i don''t know how to fix it.

推荐答案

检查是否有选择.在使用数组之前，请检查是否有选定的行.

Check if there is any selected or not. Place a check that if there is any selected row or not before you use the array.
