我有一个数据绑定的 GridView，在 button_click 我想逐行读取 GridView 每列并读取一行中每个单元格的值并更新数据库中的表?我也知道如何检查该单元格是否包含空值.

I have a GridView which is databound, on button_click I want to read the GridView row by row each column and read the value of each cell in a row and update a table in database? I also know how to check if that cell contains null.

我正在尝试这样的事情但卡住了:

I am trying something like this and got stuck:

protected void SAVE_GRID_Click(object sender, EventArgs e)
{
    int rowscount = GridView2.Rows.Count;
    int columnscount = GridView2.Columns.Count;
    for (int i = 0; i < rowscount; i++)
    {
        for (int j = 1; j < columnscount; j++)
        {
            // I want to get data of each cell in a row
            // I want to read the corresponding header and store
        }
    }       
}

推荐答案

最简单的方法是使用 foreach:

The easiest would be using a foreach:

foreach(GridViewRow row in GridView2.Rows)
{
    // here you'll get all rows with RowType=DataRow
    // others like Header are omitted in a foreach
}

根据您的编辑，您访问的列不正确，您应该从 0 开始:

According to your edits, you are accessing the column incorrectly, you should start with 0:

foreach(GridViewRow row in GridView2.Rows)
{
    for(int i = 0; i < GridView2.Columns.Count; i++)
    {
        String header = GridView2.Columns[i].HeaderText;
        String cellText = row.Cells[i].Text;
    }
}
