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();

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);
    }
  }
}

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 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。

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"];

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);
    }
