DataTable does not support schema inference from Xml.?

<?xml version="1.0" encoding="utf-8"?>
<PHP_Adapter>
  <Adapter>
    <ID>11</ID>
    <Provider>22</Provider>
    <Connectstring>33</Connectstring>
  </Adapter>
</PHP_Adapter>

This my Xml file what wrong?

    bool CheckAdapterExist(string aid)
    {
        DataTable dt = new DataTab开发者_运维百科le();
        dt.ReadXml(axml);
        MessageBox.Show(dt.Rows[0]["ID"].ToString());

        return true;
    }

Try using a Dataset rather

DataSet ds = new DataSet();
ds.ReadXml(@"d:\test.xml");
MessageBox.Show(ds.Tables[0].Rows[0]["ID"].ToString());

Found at

DataTable.ReadXml(filename) throws an error. Why?

If you're reading an XML file from DataTable.WriteXml, make sure you include an XmlWriteMode.WriteSchema.

Example:

Table.WriteXml(DataFilePath, XmlWriteMode.WriteSchema);

This works

        string XML = @"
          <MyTable>
            <MyRecord>
              <Col_1>test</Col_1>
              <Col_2>1234</Col_2>
            </MyRecord>
            <MyRecord>
              <Col_1>Record 2</Col_1>
              <Col_2>2</Col_2>
            </MyRecord>
          </MyTable>
        ";
        DataSet DS = new DataSet();
        DS.ReadXml(new StringReader(XML));

        DataTable DT=DS.Tables[0];

If you are the one writing the table, you can solve this problem by writing the schema at the same time as the table. See: http://msdn.microsoft.com/en-us/library/ms135456.aspx

Try this, this will work :

System.Xml.XmlTextReader reader =
                new System.Xml.XmlTextReader(@"C:\Users\Mayank\Documents\Projects\XMLTEST\XMLTEST\XMLFile1.xml");
            DataSet newTable = new DataSet();
            newTable.ReadXml(reader);
            DataTable _dt=newTable.Tables[0];
