Question

datagridview 点击一行数据 显示图片在PictureBox控件中。如何实现。用C#！！

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
string path=dataGridView1.Rows[dataGridView1.CurrentRow.Index ].Cells["path"].Value.ToString() ;

}
private void dataGridview1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
if (dataGridview1.Columns[e.ColumnIndex].Name.Equals("Image"))
{
string path = e.Value.ToString();
e.Value = GetImage(path);
}
}
public System.Drawing.Image GetImage(string path)
{
System.IO.FileStream fs = new System.IO.FileStream(path, System.IO.FileMode.Open);
System.Drawing.Image result = System.Drawing.Image.FromStream(fs);
fs.Close();
return result;
}
有什么问题吗？

Answer 1

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
string path=dataGridView1.Rows[dataGridView1.CurrentRow.Index ].Cells["path"].Value.ToString() ;
System.IO.FileStream fs = new System.IO.FileStream(path, System.IO.FileMode.Open);
图片控件.Image= System.Drawing.Image.FromStream(fs);
fs.Close();
}若希望程序更健壮，可以给图片读取套上try
