c# - 无法按索引访问 DataGridViewRow 单元格

Question

我正在尝试遍历 DataGridView 中的两列并将它们添加到如下坐标中

foreach (DataGridView row in dataGridView1.Rows)
{
    double x = Convert.ToDouble(row["X"]);
    double y = Convert.ToDouble(row["Y"]);
    Coordinate c = new Coordinate(x, y);
    Point p = new Point(c);
    IFeature currentFeature = fs.AddFeature(p);
    for (int i = 0; i < dataGridView1.Columns.Count; i++)
    {
        currentFeature.DataRow[i] = row[i];
    }
}

但我遇到了以下错误:

Cannot apply indexing with [] to an expression of type 'System.Windows.Forms.DataGridViewRow'

你能告诉我为什么会这样吗？

问候，

这很简单 - DataGridViewRow 类不公开索引器。您需要通过其 Cells 集合访问单元格。 row.Cells[i] 应该可以解决这个问题:

for (int i = 0; i < dataGridView1.Columns.Count; i++)
{
   currentFeature.DataRow[i] = row.Cells[i].Value as IConvertible;
}
