Finding all properties and subproperties of an object
Sometimes I want to know if an object has a property that I am looking for but sometimes an object has a lot of properties and it may take some time to find it debugging it. It will be nice if I could write a function that will find all the properties and its values in a a string then I can paste that string in notepad for instance and look for the value that I am looking for with the find feature that notepad has. So far I have something like this:
public void getAllPropertiesAndSubProperties(System.Reflection.PropertyInfo[] properties)
{
foreach (var a in properties)
{
//MessageBox.Show(a.ToString());
开发者_如何学编程 // do something here to test if property a is the one
// I am looking for
System.Reflection.PropertyInfo[] temp = a.GetType().GetProperties();
// if property a has properties then call the function again
if (temp.Length > 0) getAllPropertiesAndSubProperties(temp);
}
}
Editing the question I have worked:
so far I have added the following code. I can pass whatever object I want to the following method and I can see all the properties. I am having trouble viewing the values of the properties
![public void stackOverex(dynamic obj)
{
// this is the string where I am apending all properties
string stringProperties = "";
Type t = obj.GetType();
List<PropertyInfo> l = new List<PropertyInfo>();
while (t != typeof(object))
{
l.AddRange(t.GetProperties());
t = t.BaseType;
var properites = t.GetType().GetProperties();
foreach (var p in properites)
{
string val = "";
try
{
val = obj.GetType().GetProperty(p.Name).GetValue(obj, null).ToString();
}
catch
{
}
stringProperties += p.Name + " - " + val + "\r\n";
}
}
MessageBox.Show(stringProperties);
}
Yeah visual studio debugger is great but look how many properties an object can have. I am actually looking for the indexSomething property of a gridViewColumnHeader I don't remember the exact name I just remember I have used it before. I have an event that fires when a column gets clicked and I would like to know the index not the name "column number 2? or 3 was clicked". I know I can get it with the name but it will be nice if I can implement this debugger function. See how complex it can get in the picture below.
If you want all properties including of base type then you could do this:
Type t = typeof(AnyType);
List<PropertyInfo> l = new List<PropertyInfo>();
while (t != typeof(object))
{
l.AddRange(t.GetProperties());
t = t.BaseType;
}
or maybe you want a recursive print of properties, up to a level:
public static void ReadALotOfValues(StringBuilder b, object o, int lvl, int maxLvl)
{
Type t = o.GetType();
List<PropertyInfo> l = new List<PropertyInfo>();
while (t != typeof(object))
{
l.AddRange(t.GetProperties());
t = t.BaseType;
}
foreach (var item in l)
{
if (item.CanRead && item.GetIndexParameters().Length == 0)
{
object child = item.GetValue(o, null);
b.AppendFormat("{0}{1} = {2}\n", new string(' ', 4 * lvl), item.Name, child);
if (lvl < maxLvl)
ReadALotOfValues(b, child, lvl + 1, maxLvl);
}
}
}
EDIT: Calling the above method:
object o = ...some object here...;
var b = new StringBuilder();
ReadALotOfValues(b, o, 0, 5);
Console.WriteLine(b.ToString());
The above will read properties of up to 5 levels of depth into the objeto.
The search must be limited somehow, otherwise it would loop forever... think of a self-referencing object.
