changing the property of class file at run time

how to change the property name of class file at run time which is being used as property in propertygrid

ex)

public class propertygrid_sample
{
    string m_DisplayString;

    public string Text
    {
        get { return m_DisplayString; }
        set { m_DisplayString = value; }
    }

    //some code to change the name

}

It sounds like you're looking for something like this:

Use the display name attribute

[DisplayName("Other Name")]
public string Text { ... }

You need custom TypeDescriptor attached to your class via attribute TypeDescriptionProviderAttribute.

In your custom TypeDescriptor class you need override method GetProperties() and return edited instances of PropertyDescriptor class.

All of *Descriptor classes are meta-data classes supposed to propagating the types/members with changes - such as renaming the type/member.

Some samples with *Descriptor classes:
