使用变量调用动态方法/参数 [英] Use variables to call dynamic methods / parameters

问题描述

你好，

我正在尝试从动态对象动态获取所有属性及其值.
这是我到目前为止的代码:

Hi there,

I''m trying to dynamically get all properties and their values from dynamic objects.
This is the code I have so far:

//The code that should show the parameter and the parameter value
class MdlObject
{
    public void Insert(dynamic anObject)
    {
        var propertyInfos = anObject.GetType().GetProperties();
        // sort properties by name
        // write property names
        foreach (var propertyInfo in propertyInfos)
        {
            //this works perfect, returns Name and Id
            MessageBox.Show(propertyInfo.Name);
            //Gives an error, because it literally calls "anObject.propertyInfo.Name"
            MessageBox.Show(anObject.propertyInfo.Name);
            //This works, thanks Nishant Sivakumar :)
            MessageBox.Show(propertyInfo.GetValue(anObject, null).ToString());

        }
    }

//Example of a simple object I want to put in
class Mdltest
{
    public String Name { get; set; }
    public int Id { get; set; }
}

//Example of how to call it
var test= new Mdltest{Id = 10, Name = "just testing"};
var tmp = new MdlObject();
tmp.Insert(test);

有人可以告诉我如何修复"anObject.propertyInfo.Name"部分吗?因为当我使用它时，它实际上是调用"anObject.propertyInfo.Name"，而不是例如anObject.Name和anObject.Id ...

预先感谢您的帮助:)

Could someone tell me how I''m suppose to fix the "anObject.propertyInfo.Name" part? because when I use that it literally calls "anObject.propertyInfo.Name", and not for example anObject.Name and anObject.Id ...

Thanks in advance for the help :)

推荐答案

那行不通，您可以这样操作:

That won''t work, you can do it this way:

class MdlObject
{
    public void Insert(dynamic anObject)
    {
        var propertyInfos = anObject.GetType().GetProperties();
        foreach (var propertyInfo in propertyInfos)
        {
            MessageBox.Show(propertyInfo.Name);
        }

        MessageBox.Show(anObject.Name);
        MessageBox.Show(anObject.Id.ToString());
    }
}

或执行以下操作:

Or do this:

foreach (var propertyInfo in propertyInfos)
{
    MessageBox.Show(propertyInfo.Name);
    MessageBox.Show(propertyInfo.GetValue(anObject, null).ToString());
}

您需要在PropertyInfo上调用GetValue方法，传入要查询的对象.

You need to call the GetValue method on the PropertyInfo, passing in the object you want to query.
