將XML數據保存到SQL Server表

Question

我有這個xml文件，我想將值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> 

這是我的代碼：

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"); 

我得到這個錯誤：

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

在行：

cmd.ExecuteNonQuery();

你逝去的 '文檔'，這是你的XDocument，放入參數中。嘗試改變

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

到

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