XML到linq查询，在Windows phone中字母以a开头

本文关键字：开头 phone Windows linq 查询 XML | 更新日期: 2023-09-27 18:11:58

我试图获取数据，其中所有单词以A开头，并使用xml向LINQ显示它的列表框，但Startwith属性我无法在这里实现是我试图获取的代码

XDocument loadedCustomData = XDocument.Load("accounts.xml");
            var filteredData =
               from c in loadedCustomData.Descendants("record")
               where  (string)c.Element("main") == "Above the Line"
                // i want here something like
                //where (string)c.element("main").startwith ==a
                //so how to ACHIEVE THIS????
               select new words()
               {
                   PON = "Post Office: " + (string)c.Element("main"),
                   PIN = "Pincode (Postal Code): " + (string)c.Element("def"),
               };
            listBox1.ItemsSource = filteredData;

这里是XML格式

 <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <data-set xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<record>
      <main>Above the Line</main>
        <def>Above the line items are those revenue and expense items that directly affect          
</record>
那么如何实现以字母A开头的查询呢

XML到linq查询，在Windows phone中字母以a开头

Try This:

    XDocument loadedCustomData = XDocument.Load("accounts.xml");
    var filteredData =
       from c in loadedCustomData.Descendants("record")
       where ((string)c.Element("main")).StartsWith("A")
       select new words()
       {
           PON = "Post Office: " + (string)c.Element("main"),
           PIN = "Pincode (Postal Code): " + (string)c.Element("def"),
       };
    listBox1.ItemsSource = filteredData;
