I m使用EF 4.3.1,我有100+环境,驱动1个基体。 在所有情况下,我都希望建立数据库,这是不可行的。
可否为实体框架设定违约行为?

//Gather all the DbContexts types in the assembly
var allDbContextsTypes = Assembly.GetExecutingAssembly().GetTypes().Where(t => t.BaseType == (typeof(DbContext))).ToList();
foreach (Type dbContextType in allDbContextsTypes)
{
//Get the SetInitializerMethod
MethodInfo initializerMethod = typeof(Database).GetMethod("SetInitializer");
//Make it generic! (Oh yeah)
MethodInfo dbContextInitializerMethod = initializerMethod.MakeGenericMethod(dbContextType);
//Invoke the method with null initializer
dbContextInitializerMethod.Invoke(null, new object[]{null});
}
In the end, it gives something like : Database.SetInitializer<YourDbContext>(null);
where YourDbContext is the current dbContext type in your loop
<代码>Database.SetInitializer<TContext>是你之后的。 这种做法也是无效的,应当加以区别。

您可更改以下表格:.config文档,以取代数据库的初始化。 这是根据具体情况进行的,但可能是为了你的基本情况。
