如何获得“行”？在ReportDataSource里面？ [英] How can I get the "Row" inside ReportDataSource?

问题描述

我有以下代码：



ReportDataSource [] _reportDataSources = new ReportDataSource [1];

_reportDataSources [0] = GetDeviceHistoryData（unitheaderid）;



如何在其中获得行？当我在调试期间鼠标悬停在_reportDataSources [0]上时，我可以获得Value，而在Value中我有Row。我希望获得行计数。

如果count为0，那么我将完成我的逻辑。

我已尝试过以下但行无法出现：



if（_reportDataSources [0] .Value .....）{}



之后值，然后它不会显示Row供我选择。

Hi, I have the following codes:

ReportDataSource[] _reportDataSources = new ReportDataSource[1];
_reportDataSources[0] = GetDeviceHistoryData(unitheaderid);

How can I get the "Row" inside of it? When I mouse over the _reportDataSources[0] during debug, I can get "Value" and inside "Value" I have "Row". I want to get the "Row" count.
If count is 0, then I will do my logic.
I have tried below but the "Row" cannot coming out:

if(_reportDataSources[0].Value.....){}

After Value, then it will not show Row for me to select.

推荐答案

经过一番研究，我得出了以下解决方案：

Hi, after some research, I have come out with the following solution:

DataTable dtDeviceHistory = new DataTable();
dtDeviceHistory = (DataTable)_reportDataSources[0].Value;

if (!dtDeviceHistory.IsNullOrEmpty())
{
    if (dtDeviceHistory.Rows.Count > 0)
    {
        DisplayReport(_reportDataSources, _unitDto);
    }
}

希望得到一些反馈。谢谢。
