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"];

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();

在. net Standard中调用的方法已经改变(从1.6开始)。我们还可以使用c# 6的空条件操作符。

using System.Reflection; 
public static object GetPropValue(object src, string propName)
{
    return src.GetType().GetRuntimeProperty(propName)?.GetValue(src);
}

Dim NewHandle As YourType = CType(Microsoft.VisualBasic.CallByName(ObjectThatContainsYourVariable, "YourVariableName", CallType), YourType)

下面是另一种查找嵌套属性的方法，它不需要字符串告诉您嵌套路径。感谢Ed S.的单一属性方法。

    public static T FindNestedPropertyValue<T, N>(N model, string propName) {
        T retVal = default(T);
        bool found = false;

        PropertyInfo[] properties = typeof(N).GetProperties();

        foreach (PropertyInfo property in properties) {
            var currentProperty = property.GetValue(model, null);

            if (!found) {
                try {
                    retVal = GetPropValue<T>(currentProperty, propName);
                    found = true;
                } catch { }
            }
        }

        if (!found) {
            throw new Exception("Unable to find property: " + propName);
        }

        return retVal;
    }

        public static T GetPropValue<T>(object srcObject, string propName) {
        return (T)srcObject.GetType().GetProperty(propName).GetValue(srcObject, null);
    }

当你想要遍历对象中的所有属性，然后使用属性的每个值时，必须使用这段代码:

foreach (var property in request.GetType().GetProperties())
{
    var valueOfProperty = property.GetValue(properties, null);
}
