这样怎么样:

public static Object GetPropValue(this Object obj, String name) {
    foreach (String part in name.Split('.')) {
        if (obj == null) { return null; }

        Type type = obj.GetType();
        PropertyInfo info = type.GetProperty(part);
        if (info == null) { return null; }

        obj = info.GetValue(obj, null);
    }
    return obj;
}

public static T GetPropValue<T>(this Object obj, String name) {
    Object retval = GetPropValue(obj, name);
    if (retval == null) { return default(T); }

    // throws InvalidCastException if types are incompatible
    return (T) retval;
}

这将允许你使用单个字符串进入属性，就像这样:

DateTime now = DateTime.Now;
int min = GetPropValue<int>(now, "TimeOfDay.Minutes");
int hrs = now.GetPropValue<int>("TimeOfDay.Hours");

您可以将这些方法用作静态方法或扩展。

public class YourClass
{
    //Add below line in your class
    public object this[string propertyName] => GetType().GetProperty(propertyName)?.GetValue(this, null);
    public string SampleProperty { get; set; }
}

//And you can get value of any property like this.
var value = YourClass["SampleProperty"];

添加到任何类:

public class Foo
{
    public object this[string propertyName]
    {
        get { return this.GetType().GetProperty(propertyName).GetValue(this, null); }
        set { this.GetType().GetProperty(propertyName).SetValue(this, value, null); }
    }

    public string Bar { get; set; }
}

然后，你可以使用as:

Foo f = new Foo();
// Set
f["Bar"] = "asdf";
// Get
string s = (string)f["Bar"];

下面的方法非常适合我:

class MyClass {
    public string prop1 { set; get; }

    public object this[string propertyName]
    {
        get { return this.GetType().GetProperty(propertyName).GetValue(this, null); }
        set { this.GetType().GetProperty(propertyName).SetValue(this, value, null); }
    }
}

获取属性值:

MyClass t1 = new MyClass();
...
string value = t1["prop1"].ToString();

设置属性值。

t1["prop1"] = value;

使用微软的CallByName怎么样?VisualBasic命名空间(Microsoft.VisualBasic.dll)?它使用反射来获取普通对象、COM对象甚至动态对象的属性、字段和方法。

using Microsoft.VisualBasic;
using Microsoft.VisualBasic.CompilerServices;

然后

Versioned.CallByName(this, "method/function/prop name", CallType.Get).ToString();

 public static object GetPropValue(object src, string propName)
 {
     return src.GetType().GetProperty(propName).GetValue(src, null);
 }

当然，您会想要添加验证和诸如此类的东西，但这就是它的要点。
