我决定将我的项目从工作转移到家庭，并且在连接数据库时遇到了一些麻烦。此作品适用于工作：

web.config：

  <connectionStrings>
    <add name="ApplicationServices" connectionString="Data Source=XXXXXX\SQLSERVER2008;Persist Security Info=true;Initial Catalog=esResearch;User ID=XXXXXX; Password=XXXXXX"
        providerName="System.Data.SqlClient" />
    <add name="esResearchConnectionString" connectionString="Data Source=XXXXXX\SQLSERVER2008;Initial Catalog=esResearch;Persist Security Info=True;User ID=XXXXXX;Password=XXXXXX"
        providerName="System.Data.SqlClient" />
  </connectionStrings>

app.config：

<connectionStrings>
    <add name="esResearchModels.Properties.Settings.esResearchConnectionString"
        connectionString="Data Source=XXXXXX\SQLSERVER2008;Initial Catalog=esResearch;Persist Security Info=True;User ID=XXXXXX"
        providerName="System.Data.SqlClient" />
    <add name="esResearchModels.Properties.Settings.esResearchConnectionString1"
        connectionString="Data Source=XXXXXX\SQLSERVER2008;Initial Catalog=esResearch;Persist Security Info=True;User ID=XXXXXX;Password=XXXXXX"
        providerName="System.Data.SqlClient" />
    <add name="esResearchModels.Properties.Settings.esResearchConnectionString2"
        connectionString="Data Source=XXXXXX\SQLSERVER2008;Initial Catalog=esResearch;User ID=XXXXXX;Password=XXXXXX"
        providerName="System.Data.SqlClient" />
</connectionStrings>

我想我不需要所有这些字符串，但它至少可以工作。这行用于designer.cs

base(global::esResearchModels.Properties.Settings.Default.esResearchConnectionString2, mappingSource)

我已经在asp.net/mvc上完成了电影示例项目，并使用了这个连接字符串，并且这个可以在我家里的计算机上使用。

Web.config：

  <connectionStrings>
    <add name="ApplicationServices"
         connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true"
         providerName="System.Data.SqlClient" />

    <add name="MovieDBContext"
        connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;database=Movies;User ID=sa;password=" 
         providerName="System.Data.SqlClient"/>
  </connectionStrings>

有任何想法吗？
