从 Gridview 中求和行

Question

我是运行一个SQL查询并将结果返回到gridview。我想在 gridview 的页脚行中显示总计。一切都很完美，除了我在 gridview 中将其格式化为 % 的列。这就是我将其格式化为 percetage

的方式

<asp:BoundField DataField="percentage" HeaderText="P" DataFormatString="{0:P}" />

并抛出以下错误消息：

input string was not in correct format

我是这样称呼它的

protected void analysispack1_DataBound(object sender, EventArgs e)
{
    if (analysispack1.Rows.Count > 0)
    {
        decimal showit = 0;
        foreach (GridViewRow row in analysispack1.Rows)
        {
            showit += Convert.ToDecimal(row.Cells[2].Text);
        }
        try { analysispack1.FooterRow.Cells[0].Text = tmpDailAttendance.ToString(); }
        catch (Exception exception) { throw exception; }
    }
}

Answer 1

像这样更改您的代码

foreach (GridViewRow row in analysispack1.Rows)
{
    showit += Convert.ToDecimal(row.Cells[2].Text.Replace("%", string.Empty));
}
