我有一个上下文,我想保存上下文中每个数据集中的所有数据,我不想根据每个类类型编写代码。所以我希望有我想要保存它们的类型列表,我想在context.dataset中使用循环然后循环这些属性。
你能帮帮我吗?
public static void saveAllFiles(Context context)
{
var objectTypes = new List<Type>();
objectTypes.Add(typeof(Language));
objectTypes.Add(typeof(Employee));
foreach(Type objectType in objectTypes)
{
//var properties = objectType.GetProperties();
var properties = objectType.GetProperties(BindingFlags.Instance | BindingFlags.Public);
var dataSetObjects = context.Set<objectType>().ToList();
foreach(var dataSetObject in dataSetObjects)
{
foreach( var property in properties)
{
var value = property.GetValue(dataSetObject);
var name= property.Name;
}
}
}
}

我不确定您的Context
所指的是哪个类,但是这里有一些代码可以让您了解如何获取属性名称和值:
public static void saveAllFiles(Context context)
{
var objectTypes = new List<Type> {typeof (int), typeof (string)};
foreach(Type objectType in objectTypes)
{
var properties = objectType.GetProperties(BindingFlags.Instance | BindingFlags.Public);
var dataSetObjects = context.Set(objectType);
foreach(var dataSetObject in dataSetObjects)
{
foreach( var property in properties )
{
var value = property.GetValue(dataSetObject);
var name = property.Name;
}
}
}
}
