Question

lastbudget和lastactual都是列表

这些列表填充了基础设施超网格中的2列

PrevFY
Actual_c

因此，网格已经定义了数据源。我以编程方式将这两列添加到了具有数据源的网格中。

（dgvBudget是超网格的名称）

int rowIndex = dgvBudget.Rows.Count;


if (half == "Second Half Budget")
{
    for (int i = 6; i < rowIndex; i++)
    {
        var row = dgvBudget.Rows[i];
        row.Cells["PrevFY"].Value = lastbudget[i];
        row.Cells["Actual_c"].Value = lastactual[i];
    }
    for (int i = 0; i < 6; i++)
    {
        var row = dgvBudget.Rows[i];
        row.Cells["PrevFY"].Value = lastactual[i];
        row.Cells["Actual_c"].Value = 0;
    }
}
else
{
    for (int i = 0; i < rowIndex; i++)
    {
        var row = dgvBudget.Rows[i];
        row.Cells["PrevFY"].Value = lastbudget[i];
        row.Cells["Actual_c"].Value = lastactual[i];
    }
}

我的目标是创建一个新的数据源，并使用我创建的3个新列将绑定的数据导入到datagridview中，以在执行时减少MS。

目前执行过程需要8到10秒

private void bringPreviousData()
{
    Stopwatch stopwatch = Stopwatch.StartNew();
    List<string> lastactual = new List<string>();
    List<string> lastbudget = new List<string>();
    Control cmbBudgetCode = csm.GetNativeControlReference("17dd127e-7b02-48e9-a7bb-e98164aea713");
    EpiDataView bhView = (EpiDataView)(oTrans.EpiDataViews["GLBudgetHd"]);
    if (!dgvBudget.DisplayLayout.Bands[0].Columns.Exists("PrevFY"))
    {
        dgvBudget.DisplayLayout.Bands[0].Columns.Add("PrevFY", "Previous FY Budgeted");
        dgvBudget.DisplayLayout.Bands[0].Columns["PrevFY"].Style = Infragistics.Win.UltraWinGrid.ColumnStyle.Currency;
    }

    if (!dgvBudget.DisplayLayout.Bands[0].Columns.Exists("FiscalMonth"))
    {
        dgvBudget.DisplayLayout.Bands[0].Columns.Add("FiscalMonth", "Month");
        SetColumnReadOnly("FiscalMonth", true);
    }
    else
    {
        string[] monthNames = { "April", "May", "June", "July", "August", "September", "October", "November", "December", "January", "February", "March" };
        for (int i = 0; i < monthNames.Length; i++)
        {
            dgvBudget.Rows[i].Cells["FiscalMonth"].Value = monthNames[i];
        }
    }

    string half = cmbBudgetCode.Text;
    lastactual = GetLastActual(half);
    lastbudget = GetLastBudget(half);
    int rowIndex = dgvBudget.Rows.Count;
    if (half == "Second Half Budget")
    {
        for (int i = 6; i < rowIndex; i++)
        {
            var row = dgvBudget.Rows[i];
            row.Cells["PrevFY"].Value = lastbudget[i];
            row.Cells["Actual_c"].Value = lastactual[i];
        }
        for (int i = 0; i < 6; i++)
        {
            var row = dgvBudget.Rows[i];
            row.Cells["PrevFY"].Value = lastactual[i];
            row.Cells["Actual_c"].Value = 0;
        }
    }
    else
    {
        for (int i = 0; i < rowIndex; i++)
        {
            var row = dgvBudget.Rows[i];
            row.Cells["PrevFY"].Value = lastbudget[i];
            row.Cells["Actual_c"].Value = lastactual[i];
        }
    }

    decimal total = 0m;
    foreach (UltraGridRow row in dgvBudget.Rows)
    {
        total += Convert.ToDecimal(row.Cells["PrevFY"].Value);
    }
    if (Config.typeofAccount != "Overtime")
    {
        if (GetAcctType(bhView.CurrentDataRow["SegValue1"].ToString()))
        {
            nbrPrevStatTotal.Value = total;
        }
        else
        {
            nbrPrevTotal.Value = total;
        }
    }
    else
    {
        nbrPrevTotal.Value = total;
    }
    stopwatch.Stop();
    MessageBox.Show(stopwatch.ElapsedMilliseconds.ToString());
}

因此，此代码目前正在执行

获取2个数据列表
然后添加两列（如果不存在）（prevFy和FiscalMonth）
然后使用当前数据源以及我添加的数据和列填充超网格视图
然后将单元格中的值求和以显示在文本框中

请问我如何加快速度，因为现在它可以工作了，真是太好了，谢谢！

将现有数据添加到具有更多数据的新数据表中
