将XML数据保存到SQL Server表

I have this xml file, and I want to save value NUMBER (for example) to a SQL Server table.

我有这个xml文件,我想将值NUMBER(例如)保存到SQL Server表。

<ORDER>
  <ORDER_HEADER>
    <NUMBER>10945</NUMBER>
    <TIME>7.8.2013 12:45:20</TIME>
    <NOTE>this is Note</NOTE>   
  </ORDER_HEADER>
</ORDER> 

This is my code:

这是我的代码:

XDocument doc = XDocument.Load("C:\\Users\\L\\Desktop\\data.xml");
var NUMBER = doc.Descendants("NUMBER");
var TIME = doc.Descendants("TIME");
var NOTE = doc.Descendants("NOTE");

foreach (var cislo in NUMBER)
{
    SqlConnection conn = new SqlConnection("Data Source=***");
    conn.Open();

    using (SqlCommand cmd = conn.CreateCommand())
    {
       cmd.CommandText = "Update CISLO SET cislo = @cislo1;";
       cmd.Parameters.AddWithValue("@cislo1", doc);

       cmd.ExecuteNonQuery();
    }
 }

 MessageBox.Show("OK");

I get this error:

我收到此错误:

There is no mapping from object type System.Xml.Linq.XDocument to a known managed provider native type.

从对象类型System.Xml.Linq.XDocument到已知的托管提供程序本机类型没有映射。

On row:

cmd.ExecuteNonQuery();

You are passing 'doc', which is your XDocument, into the parameter. Try changing

您将'doc'(您的XDocument)传递给参数。尝试改变

cmd.Parameters.AddWithValue("@cislo1", doc);

to

cmd.Parameters.AddWithValue("@cislo1", cislo);
