最佳答案
下面是我用来获取 IsDirty 检查类中所有公共属性的初始状态的一些代码。
What's the easiest way to see if a property is IEnumerable?
干杯,
Berryl
protected virtual Dictionary<string, object> _GetPropertyValues()
{
return _getPublicPropertiesWithSetters()
.ToDictionary(pi => pi.Name, pi => pi.GetValue(this, null));
}
private IEnumerable<PropertyInfo> _getPublicPropertiesWithSetters()
{
return GetType().GetProperties().Where(pi => pi.CanWrite);
}
我最后要做的是添加一些库扩展,如下所示
public static bool IsNonStringEnumerable(this PropertyInfo pi) {
return pi != null && pi.PropertyType.IsNonStringEnumerable();
}
public static bool IsNonStringEnumerable(this object instance) {
return instance != null && instance.GetType().IsNonStringEnumerable();
}
public static bool IsNonStringEnumerable(this Type type) {
if (type == null || type == typeof(string))
return false;
return typeof(IEnumerable).IsAssignableFrom(type);
}
