如何在winform的datagridview的列image列中显示图象

Answer 1

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;

}
使用DataGridViewImageColumn
DataGridViewImageColumn column = new DataGridViewImageColumn();
dataGridView1.Columns.Add(column);
column.HeaderText = "图片";
column.Image = System.Drawing.Image.FromFile("路径");

((DataGridViewImageCell)this.dataGridView1.Rows[e.RowIndex].Cells[ "图片列"]).Value = "路经 "
