[RESOLVED] Getting All Properties Of A Control

Hi I have a webbrowser on my form and having problem with getting its values. I followed the page Question about How to loop through all the properties of a class

VB.NET Code:

Type type = Browser_Wb.GetType();
 
PropertyInfo[] properties = type.GetProperties();
 
foreach (PropertyInfo property in properties)
{
    Console.WriteLine("Name: " + property.Name + ", Value: " + property.GetValue(Browser_Wb));
}

And

VB.NET Code:

Type type = Browser_Wb.GetType();
 
BindingFlags flags = BindingFlags.Public | BindingFlags.Instance;
PropertyInfo[] properties = type.GetProperties(flags);
 
foreach (PropertyInfo property in properties)
{
    Console.WriteLine("Name: " + property.Name + ", Value: " + property.GetValue(Browser_Wb, null));
}

I got error: System.ArgumentException: 'Property Get method was not found.'

Not all properties are read and write, some are read-only (no set), and some are write-only (no get). It seems you have found one that is write-only.

To avoid the error for that property (and any others that are write-only), you can apparently check if the get is available (using property.GetGetMethod()), which you should do before trying to call it, eg:

Code:

---

    if (property.GetGetMethod() != null)
        Console.WriteLine("Name: " + property.Name + ", Value: " + property.GetValue(Browser_Wb, null));
    else
        Console.WriteLine("Name: " + property.Name + ", value is write-only";

---

Thank that helped a lot.

If you want to ignore the write-only properties, you could include the check for getter in the loop statement:

csharp Code:

PropertyInfo[] properties = type.GetProperties();
 
foreach (PropertyInfo property in properties.Where(pi => pi.GetMethod() != null))

By the way, note that I used "csharp" as the option for the HIGHLIGHT tag to get syntax-highlighting appropriate to C#.
