我想通过代码更改const userId = 123;
const userName = 'john'
const url = `/foo/${userId}/${userName}`;
console.log(url);中的ConnectionString。
app.config：
app.config代码：
<connectionStrings>
<add name="MyEntities"
connectionString="metadata=res://*/MyEntities.csdl|res://*/MyEntities.ssdl|res://*/MyEntities.msl;provider=System.Data.SqlClient;provider connection string="data source=SomeServer\SomeInstance;initial catalog=SomeDatabase;persist security info=True;user id=USER_123;password=123;MultipleActiveResultSets=True;App=EntityFramework""
providerName="System.Data.EntityClient" />
</connectionStrings>
可悲的是，我得到了private void ApplyAppConfig(EnvironmentConfig envConfig)
{
string connectionString = $"metadata=res://*/{envConfig.Database}.csdl|res://*/{envConfig.Database}.ssdl|res://*/M42Production.msl;provider=System.Data.SqlClient;provider" +
$@" connection string='data source={envConfig.DatabaseServer};initial catalog={envConfig.Database};persist security info=True;user id={envConfig.DatabaseUser};password={envConfig.DatabasePassword};" +
"MultipleActiveResultSets=True;App=EntityFramework'";
var config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
var connectionStringsSection = (ConnectionStringsSection)config.GetSection("connectionStrings");
connectionStringsSection.ConnectionStrings["MyEntities"].ConnectionString = connectionString;
config.Save();
ConfigurationManager.RefreshSection("connectionStrings");
}

Exception我已经尝试过this，但没有成功。
还有什么我想念的吗？
