強類型數據集Adapter.Update不插入行

我有下面的代碼（根據guide）應該插入一個記錄到我的強類型數據集，並依次我的數據庫。但是，記錄不會輸入到數據庫中，但會正確輸入到數據集中。我錯過了一個命令？強類型數據集Adapter.Update不插入行

using (Dataset1TableAdapters.AddressTableAdapter addressAdapter = new Dataset1TableAdapters.AddressTableAdapter()) 
{ 
    using (Dataset1.AddressDataTable addresses = new Dataset1.AddressDataTable()) 
    { 
     // Create a new address. 
     Dataset1.AddressRow address = addresses.NewAddressRow(); 

     // Set some data. 
     address.Address1 = "test1"; 
     address.Address2 = "test2"; 
     address.Address3 = "test3"; 
     address.UserID = 1; 

     // Add new address to address table. 
     addresses.AddAddressRow(address); 

     // Update the database with all the changes. 
     addressAdapter.Update(addresses); 
    } 
}

乾杯，保羅。
