看看Heleonix。反映图书馆。你可以通过路径获取/设置/调用成员，或者创建一个getter/setter (lambda编译成委托)，这比反射更快。例如:

var success = Reflector.Get(DateTime.Now, null, "Date.Year", out int value);

或者只创建一个getter并缓存以供重用(这样性能更好，但如果中间成员为空可能会抛出NullReferenceException):

var getter = Reflector.CreateGetter<DateTime, int>("Date.Year", typeof(DateTime));
getter(DateTime.Now);

或者如果你想创建一个List<Action<object, object>>的不同getter，只需要为已编译的委托指定基本类型(类型转换将被添加到已编译的lambdas中):

var getter = Reflector.CreateGetter<object, object>("Date.Year", typeof(DateTime));
getter(DateTime.Now);

捷径....

var a = new Test { Id = 1 , Name = "A" , date = DateTime.Now};
var b = new Test { Id = 1 , Name = "AXXX", date = DateTime.Now };

var compare = string.Join("",a.GetType().GetProperties().Select(x => x.GetValue(a)).ToArray())==
              string.Join("",b.GetType().GetProperties().Select(x => x.GetValue(b)).ToArray());

public static TValue GetFieldValue<TValue>(this object instance, string name)
{
    var type = instance.GetType(); 
    var field = type.GetFields(BindingFlags.NonPublic | BindingFlags.Static | BindingFlags.Instance).FirstOrDefault(e => typeof(TValue).IsAssignableFrom(e.FieldType) && e.Name == name);
    return (TValue)field?.GetValue(instance);
}

public static TValue GetPropertyValue<TValue>(this object instance, string name)
{
    var type = instance.GetType();
    var field = type.GetProperties(BindingFlags.NonPublic | BindingFlags.Static | BindingFlags.Instance).FirstOrDefault(e => typeof(TValue).IsAssignableFrom(e.PropertyType) && e.Name == name);
    return (TValue)field?.GetValue(instance);
}

 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。

如果我用Ed s的密码，我就

“ReflectionExtensions。由于其保护级别，GetProperty(Type, string)'不可访问

似乎GetProperty()在Xamarin.Forms中不可用。TargetFrameworkProfile是我的便携式类库中的Profile7。NET Framework 4.5, Windows 8, ASP。NET Core 1.0, Xamarin。Android, Xamarin的。Xamarin的iOS。iOS经典)。

现在我找到了一个可行的解决方案:

using System.Linq;
using System.Reflection;

public static object GetPropValue(object source, string propertyName)
{
    var property = source.GetType().GetRuntimeProperties().FirstOrDefault(p => string.Equals(p.Name, propertyName, StringComparison.OrdinalIgnoreCase));
    return property?.GetValue(source);
}

源

下面的代码是一个递归方法，用于显示对象实例中包含的所有属性名称和值的整个层次结构。这个方法在这个线程中使用了AlexD的GetPropertyValue()答案的简化版本。多亏了这个讨论帖，我才知道该怎么做!

例如，我使用这个方法来显示WebService响应中所有属性的爆炸或转储，如下所示:

晚点属性(“响应”、“响应”、“错误”);

public static object GetPropertyValue(object srcObj, string propertyName)
{
  if (srcObj == null) 
  {
    return null; 
  }
  PropertyInfo pi = srcObj.GetType().GetProperty(propertyName.Replace("[]", ""));
  if (pi == null)
  {
    return null;
  }
  return pi.GetValue(srcObj);
}

public static void PropertyValues_byRecursion(string parentPath, object parentObj, bool showNullValues)
{
  /// Processes all of the objects contained in the parent object.
  ///   If an object has a Property Value, then the value is written to the Console
  ///   Else if the object is a container, then this method is called recursively
  ///       using the current path and current object as parameters

  // Note:  If you do not want to see null values, set showNullValues = false

  foreach (PropertyInfo pi in parentObj.GetType().GetTypeInfo().GetProperties())
  {
    // Build the current object property's namespace path.  
    // Recursion extends this to be the property's full namespace path.
    string currentPath = parentPath + "." + pi.Name;

    // Get the selected property's value as an object
    object myPropertyValue = GetPropertyValue(parentObj, pi.Name);
    if (myPropertyValue == null)
    {
      // Instance of Property does not exist
      if (showNullValues)
      {
        Console.WriteLine(currentPath + " = null");
        // Note: If you are replacing these Console.Write... methods callback methods,
        //       consider passing DBNull.Value instead of null in any method object parameters.
      }
    }
    else if (myPropertyValue.GetType().IsArray)
    {
      // myPropertyValue is an object instance of an Array of business objects.
      // Initialize an array index variable so we can show NamespacePath[idx] in the results.
      int idx = 0;
      foreach (object business in (Array)myPropertyValue)
      {
        if (business == null)
        {
          // Instance of Property does not exist
          // Not sure if this is possible in this context.
          if (showNullValues)
          {
            Console.WriteLine(currentPath  + "[" + idx.ToString() + "]" + " = null");
          }
        }
        else if (business.GetType().IsArray)
        {
          // myPropertyValue[idx] is another Array!
          // Let recursion process it.
          PropertyValues_byRecursion(currentPath + "[" + idx.ToString() + "]", business, showNullValues);
        }
        else if (business.GetType().IsSealed)
        {
          // Display the Full Property Path and its Value
          Console.WriteLine(currentPath + "[" + idx.ToString() + "] = " + business.ToString());
        }
        else
        {
          // Unsealed Type Properties can contain child objects.
          // Recurse into my property value object to process its properties and child objects.
          PropertyValues_byRecursion(currentPath + "[" + idx.ToString() + "]", business, showNullValues);
        }
        idx++;
      }
    }
    else if (myPropertyValue.GetType().IsSealed)
    {
      // myPropertyValue is a simple value
      Console.WriteLine(currentPath + " = " + myPropertyValue.ToString());
    }
    else
    {
      // Unsealed Type Properties can contain child objects.
      // Recurse into my property value object to process its properties and child objects.
      PropertyValues_byRecursion(currentPath, myPropertyValue, showNullValues);
    }
  }
