使用自定义类作为参数从 MethodInfo 调用方法

发布于 2024-12-31 22:27:00 字数 536 浏览 4 评论 0原文

我有这样的场景：一个具有一些属性的自定义类（客户），如下所示：

public class Customer
{
    public int Handler { get; set; }
    public string Name { get; set; }
}

一个具有方法的自定义类，如下所示：

public class CustomerMethods
{
    public static void Insert(Customer customer)
    {
        //Do Something...
    }
}

因此，我将加载一个包含一些信息的文本文件，例如类名称、属性名称和属性值。但是，真正的问题是，在设置 Handler 和 Name 属性的值后，如何从 CustomerMethods 类调用 Insert 方法并将 Customer 类作为参数传递？

哦，我差点忘了，我试图避免条件语句，因为我有 100 多个类。 /o\ 各位，如果您需要更多信息，请告诉我...

I have this scenario:
One custom class (Customer) with some properties, like this:

public class Customer
{
    public int Handler { get; set; }
    public string Name { get; set; }
}

One custom class with the Method, like this:

public class CustomerMethods
{
    public static void Insert(Customer customer)
    {
        //Do Something...
    }
}

So, I will load a text file with some info, like class name, property name and property value.
But, the real problem is, how can I invoke the Insert Method from CustomerMethods class and pass Customer class as parameter after set the values of Handler and Name properties?

Oh, I almost forget, I am trying to avoid conditionals, because I have 100+ classes. /o\
Ty all, if you need more info, just tell me plz...

typeof(CustomerMethods).GetMethod(SomeName).Invoke(null, new Customer(...))

但是，如果可能的话，您应该尝试重构您的设计并避免这种情况。

typeof(CustomerMethods).GetMethod(SomeName).Invoke(null, new Customer(...))

However, you should try to refactor your design and avoid this, if possible.

我仅使用这些字符串来调用静态插入方法 WindowsFormsApplication1.Form1+CustomerMethods WindowsFormsApplication1.Form1+Customer 插入

Type customerMethodsType = Type.GetType("WindowsFormsApplication1.Form1+CustomerMethods");
Type customerType = Type.GetType("WindowsFormsApplication1.Form1+Customer");
object customerObject =  Activator.CreateInstance(customerType);

customerType.GetProperty("Handler").SetValue(customerObject, 3, null);

customerMethodsType.InvokeMember(
    "Insert",
    BindingFlags.Public | BindingFlags.InvokeMethod| BindingFlags.Static,
    null,
    null,
    new object[] { customerObject }
    );

I used only these strings to call static Insert method WindowsFormsApplication1.Form1+CustomerMethods WindowsFormsApplication1.Form1+Customer Insert

Type customerMethodsType = Type.GetType("WindowsFormsApplication1.Form1+CustomerMethods");
Type customerType = Type.GetType("WindowsFormsApplication1.Form1+Customer");
object customerObject =  Activator.CreateInstance(customerType);

customerType.GetProperty("Handler").SetValue(customerObject, 3, null);

customerMethodsType.InvokeMember(
    "Insert",
    BindingFlags.Public | BindingFlags.InvokeMethod| BindingFlags.Static,
    null,
    null,
    new object[] { customerObject }
    );
