c# - 如何从变量中插入数据到数据表

Question

我想用从变量中获取的值填充 DataTable。我正在用 c# 编写代码。我有一个名为 summary 的 DataTable，我已经创建了列，我需要将值添加到变量 average、remaining_share、sales_proceed, cost_sale, realized_profit.

代码如下:

protected void Button1_Click(object sender, EventArgs e)
{
    average = 25;
    remaining_share = 30;
    sales_proceed = 125;
    cost_sale = 50;
    realized_profit = 33;
    var dataTablesummary = new DataTable();
    dataTablesummary.Columns.Add("average", typeof(decimal));
    dataTablesummary.Columns.Add("Remaining share", typeof(decimal));
    dataTablesummary.Columns.Add("sales_proceed", typeof(decimal));
    dataTablesummary.Columns.Add("cost_sale", typeof(decimal));
    dataTablesummary.Columns.Add("realized_profit", typeof(decimal));
}

我想在点击按钮时向 DataTable 添加值，请告诉我如何做。

Answer 1

考虑到 average, remaining_share, sales_proceed, cost_sale, realized_profit 是您要插入到行中的变量，以下行

dataTablesummary.Rows.Add(average, remaining_share, sales_proceed, cost_sale, realized_profit);

会做的。

protected void Button1_Click(object sender, EventArgs e)
{
    average = 25;
    remaining_share = 30;
    sales_proceed = 125;
    cost_sale = 50;
    realized_profit = 33;
    var dataTablesummary = new DataTable();
    dataTablesummary.Columns.Add("average", typeof(decimal));
    dataTablesummary.Columns.Add("Remaining share", typeof(decimal));     dataTablesummary.Columns.Add("sales_proceed", typeof(decimal));
    dataTablesummary.Columns.Add("cost_sale", typeof(decimal));
    dataTablesummary.Columns.Add("realized_profit", typeof(decimal));
    dataTablesummary.Rows.Add(average, remaining_share, sales_proceed, cost_sale, realized_profit);
}
