Registration status of the object. Getting all its property values ​​as a string

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"; 

Consider the class above, and then initialize it. Now at some point I want to record its status when an error occurs. I would like to get a string log as shown below.

 string toLog = Helper.GetLogFor(emp1Address); 

sting toLog should look something like this.

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

And then I will write the line toLog .

How can I access all property names and object property values ​​in the Helper.GetLogFor() method?

The solution I implemented: -

 /// <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()); }

You can access the property name using reflection as shown below

 Type t = emp1Address.GetType(); PropertyInfo [] pi = t.GetProperties(); foreach (PropertyInfo p in pi) { //You can get the value (using GetValue() method) and name (p.Name) here. }
