HOW TO：加入及修改具有複雜類型的物件 (Entity Framework)

本主題使用 HOW TO：定義具有複雜類型的模型 (Entity Framework) 中所設計的 Entity Data Model。

若要建立應用程式以及在儲存區中加入複雜類型

1. 建立名為 CustomerComplexAddrClient 的主控台應用程式專案。

2. 加入 System.Data.Entity 和 System.Runtime.Serialization 命名空間的參考。

3. 加入從 HOW TO：定義具有複雜類型的模型 (Entity Framework) 主題所述之專案建置之 dll 的參考。

4. 將主題 HOW TO：定義具有複雜類型的模型 (Entity Framework) 中的結構描述加入至與可執行檔相同的資料夾。

5. 建立應用程式組態檔，如底下所示。

6. 將範例程式碼加入至 Program.cs 檔案。

7. 建置及執行專案。

// The following syntax is used in the App.config file.
<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <connectionStrings>
    <add name="CustomerComplexAddressContext" 
         connectionString="metadata=.;
         provider=System.Data.SqlClient;
         provider connection string=&quot;
         Data Source=serverName;
         Initial Catalog=CustomerWComplexAddress;
         Integrated Security=True;
         multipleactiveresultsets=true&quot;"
         providerName="System.Data.EntityClient" />
  </connectionStrings>
</configuration>

範例

這裡所示的範例程式碼會建立 CCustomer 的實體及複雜類型的 CAddress。CCustomer 和 CAddress 的屬性會初始化。CAddress 會指派給 CCustomer 的 Address 屬性。CCustomer 和 CAddress 都會加入到儲存區，而且會儲存變更。
