记录对象的状态.将其所有属性值作为字符串

Question

public class Address
{
    public string AddressLine1 { get; set; }
    public string AddressLine2 { get; set; }
    public string City { get; set; }
    public string State { get; set; }
    public string Zip { get; set; }
}
......
var emp1Address = new Address();
emp1Address.AddressLine1 = "Microsoft Corporation";
emp1Address.AddressLine2 = "One Microsoft Way";
emp1Address.City = "Redmond";
emp1Address.State = "WA";
emp1Address.Zip = "98052-6399";

考虑上面的类以及稍后的初始化.现在,在某些时候,我想在发生错误时记录其状态.我想得到字符串日志有点像下面.

string toLog = Helper.GetLogFor(emp1Address);

sting toLog应该如下所示.

AddressLine1 = "Microsoft Corporation";
AddressLine2 = "One Microsoft Way";
City = "Redmond";
State = "WA";
Zip = "98052-6399";

然后我会记录toLog字符串.

如何在Helper.GetLogFor()方法中访问对象的所有属性名称和属性值？

我实施的解决方案: -

/// <summary>
/// Creates a string of all property value pair in the provided object instance
/// </summary>
/// <param name="objectToGetStateOf"></param>
/// <exception cref="ArgumentException"></exception>
/// <returns></returns>
public static string GetLogFor(object objectToGetStateOf)
{
  if (objectToGetStateOf == null)
  {
    const string PARAMETER_NAME = "objectToGetStateOf";
    throw new ArgumentException(string.Format("Parameter {0} cannot be null", PARAMETER_NAME), PARAMETER_NAME);
  }
  var builder = new StringBuilder();

  foreach (var property in objectToGetStateOf.GetType().GetProperties())
  {
    object value = property.GetValue(objectToGetStateOf, null);

        builder.Append(property.Name)
        .Append(" = ")
        .Append((value ?? "null"))
        .AppendLine();
  }
  return builder.ToString();
}

Answer 1

public static string GetLogFor(object target)
{
    var properties =
        from property in target.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance)
        select new
        {
            Name = property.Name,
            Value = property.GetValue(target, null)
        };

    var builder = new StringBuilder();

    foreach(var property in properties)
    {
        builder
            .Append(property.Name)
            .Append(" = ")
            .Append(property.Value)
            .AppendLine();
    }

    return builder.ToString();
}

Answer 2

static void Log(object @object)
{
    foreach (var property in @object.GetType().GetProperties())
        Console.WriteLine(property.Name + ": " + property.GetValue(@object, null).ToString());
}
