   public string Bar {get; set;}
}

How do I get the value of Bar, a string property, via reflection? The following code will thr

Answer 1

You can just get the property by name:

Foo f = new Foo();
f.Bar = "Jon Skeet is god.";

var barProperty = f.GetType().GetProperty("Bar");
string s = barProperty.GetValue(f,null) as string;

Regarding the follow up question: Indexers will always be named Item and have arguments on the getter. So

Foo f = new Foo();
f.Bar = "Jon Skeet is god.";

var barProperty = f.GetType().GetProperty("Item");
if (barProperty.GetGetMethod().GetParameters().Length>0)
{
    object value = barProperty.GetValue(f,new []{1/* indexer value(s)*/});
}

Answer 2

PropertyInfo propInfo = f.GetType().GetProperty("Bar");
object[] obRetVal = new Object[0];
string bar = propInfo.GetValue(f,obRetVal) as string;

Answer 3

the getvalue with object and null worked great for me. Thanks for the posts.

Context: Looping through all properties in an MVC model for New Hires and determining their form posted values:

newHire => the Model, with many properties, whose posted form values I want to write individually to a set of database records

foreach(var propertyValue in newHire.GetProperties())
{
string propName = propertyValue.Name;

string postedValue = newHire.GetType().GetProperty(propName).GetValue(newHire, null).ToString();

}
