Question

我有一个以下的xml文件：

 <Query>
        <DataSourceName>DS1</DataSourceName>
        <CommandText>SELECT FirstName,Lastname FROM Person</CommandText>
      </Query>
      <Fields>
        <Field Name="FirstName">
          <DataField>FirstName</DataField>
          <rd:TypeName>System.String</rd:TypeName>
        </Field>
        <Field Name="Lastname">
          <DataField>Lastname</DataField>
          <rd:TypeName>System.String</rd:TypeName>
        </Field>
     </Fields>

我要做的就是，我必须在节点“查询”之后将节点“字段”中的xml文本写入“/ fields”..怎么做... plz帮帮我

您可以使用Xdocument来管理xml。您可以参考以下代码段将元素添加到标记中。希望这有帮助

XDocument xdoc = XDocument.Load(test.xml");
XNamespace ns = "schemas.microsoft.com/sqlserver/reporting/2005/01";
         XNamespace ns1 = "schemas.microsoft.com/SQLServer/reporting";


         xdoc.Root.Element(ns + "Fields").Add(new XElement("Field", new XAttribute("Name","ReportId"), new XElement(ns1 + "TypeName", "System.Int64"), new XElement("DataField", "ReportId")));


xdoc.Save(test.xml");

添加命名空间在这里很重要。我附上了源文件和结果文件供您参考。

源文件：

<?xml version="1.0" encoding="utf-8"?>
<Report xmlns="schemas.microsoft.com/sqlserver/reporting/2005/01" xmlns:rd="schemas.microsoft.com/SQLServer/reporting">
  <Query>
    <DataSourceName>DS1</DataSourceName>
    <CommandText>SELECT FirstName,Lastname FROM Person</CommandText>
  </Query>
  <Fields>
    <Field Name="FirstName">
      <DataField>FirstName</DataField>
      <rd:TypeName>System.String</rd:TypeName>
    </Field>
    <Field Name="Lastname">
      <DataField>Lastname</DataField>
      <rd:TypeName>System.String</rd:TypeName>
    </Field>
  </Fields>
</Report>

结果文件：

    <?xml version="1.0" encoding="utf-8"?>
<Report xmlns="schemas.microsoft.com/sqlserver/reporting/2005/01" xmlns:rd="schemas.microsoft.com/SQLServer/reporting">
  <Query>
    <DataSourceName>DS1</DataSourceName>
    <CommandText>SELECT FirstName,Lastname FROM Person</CommandText>
  </Query>
  <Fields>
    <Field Name="FirstName">
      <DataField>FirstName</DataField>
      <rd:TypeName>System.String</rd:TypeName>
    </Field>
    <Field Name="Lastname">
      <DataField>Lastname</DataField>
      <rd:TypeName>System.String</rd:TypeName>
    </Field>
    <Field Name="ReportId" xmlns="">
      <rd:TypeName>System.Int64</rd:TypeName>
      <DataField>ReportId</DataField>
    </Field>
  </Fields>
</Report>
