C# WinForms 读取 XML 文件 - 仅特定节点
我有一个 XML 文件：
<Database>
<SMS>
<Number>+447761692278</Number>
<DateTime>2009-07-27T15:20:32</DateTime>
<Message>Yes</Message>
<FollowedUpBy>Unassigned</FollowedUpBy>
<Outcome></Outcome>
<Quantity>0</Quantity>
<Points>0</Points>
</SMS>
<SMS>
<Number>+447706583066</Number>
<DateTime>2009-07-27T15:19:16</DateTime>
<Message>STOP</Message>
<FollowedUpBy>Unassigned</FollowedUpBy>
<Outcome></Outcome>
<Quantity>0</Quantity>
<Points>0</Points>
</SMS>
</Database>
目前我使用以下方法将其读入 datagridview：
public void Read()
{
DataSet ds = new DataSet("SMS DataSet");
XmlDataDocument xmlDatadoc = new XmlDataDocument();
xmlDatadoc.DataSet.ReadXml(@"C:\Documents and Settings\Administrator\Desktop\RecSmsDB.xml");
ds = xmlDatadoc.DataSet;
this.dataGridView1.DataSource = ds;
this.dataGridView1.DataMember = "SMS";
this.dataGridView1.Sort(dataGridView1.Columns["DateTime"], ListSortDirection.Descending);
}
我希望能够仅读取具有特定日期时间的 xml 对象。 有谁知道这样做的方法吗？ 目前我已经尝试了命名空间中包含的各种方法但没有效果。
非常感谢帮助，
问候。
***编辑：我希望能够动态更改运行时显示的数据。
I have an XML File:
<Database>
<SMS>
<Number>+447761692278</Number>

<Outcome></Outcome>
<Quantity>0</Quantity>
<Points>0</Points>
</SMS>
</Database>
Currently I read it into a datagridview using this:
public void Read()
{
DataSet ds = new DataSet("SMS DataSet");
XmlDataDocument xmlDatadoc = new XmlDataDocument();
xmlDatadoc.DataSet.ReadXml(@"C:\Documents and Settings\Administrator\Desktop\RecSmsDB.xml");
ds = xmlDatadoc.DataSet;
this.dataGridView1.DataSource = ds;
this.dataGridView1.DataMember = "SMS";
this.dataGridView1.Sort(dataGridView1.Columns["DateTime"], ListSortDirection.Descending);
}
I want to be able to only read in the xml objects that have a specific DateTime. Does anyone know of a way of doing this? Currently I have tried a variety of the methods included in the namespace but to no avail.
Help greatly appreciated,
regards.
***EDIT: I want to be able to dynamically change the data displayed at run time.

我想不到。 但是，您可以将所有数据读入 DataSet，然后创建一个筛选 SMS 表的 DataView，并将网格绑定到该数据视图而不是 DataTable。
Not that I can think of. However, you can read all the data into the DataSet, then create a DataView which filters the SMS table, and bind your grid to that instead of the DataTable.
如果将 DataSet 附加到 BindingSource 并将此 BindingSource 附加到网格会怎样？ BindingSource 有一个 Filter 属性，您可以在其中输入类似 SQL 的表达式。
What if you attach the DataSet to a BindingSource and attach this BindingSource to the grid? A BindingSource has a Filter property where you can enter SQL-like expressions.
