2) with reflection<br />
<br />
<pre><br />
public object loadObject(Type TypeToLoad, Type Interface)<br />
{<br />
    Type[] ifs = TypeToLoad.GetInterfaces();<br />
    if (Array.IndexOf(ifs, Interface) == -1)<br />
    {<br />
        throw new Exception("It didn't work!");<br />
    }<br />
    return TypeToLoad.GetConstructor(null).Invoke(null);<br />
}<br />
</pre><br />

this will work with 1.1 (if you still use that one..) and it will fail *before* the instance is created. but you will have to cast the return - value to your interface type:<br />
<code>myInterface Obj = loadObject(typeof(SomeType), typeof(myInterface)) as myInterface;

FormCommon newForm=null;
if (strReportName == PRICEHISTORY) newForm=new frmHistoryDetails();
else if (strReportName == PRICEHISTORYBEST) newForm=new fmrHistory();
if (newForm!=null) {
    newForm.ReportNameGet(strReportName.ToLower());
    newForm.SecurityID = intSecurityID;// Provide the SecurityID to the new form. 
    newForm.ShowDialog();// Show the form.
    newForm.Dispose();
}

public class myClassName {
    // Deserialization
    public myClassName(SerializationInfo info, StreamingContext ctxt) {
        m_Value = (m_ValueType)info.GetValue("Whatever", typeof(m_ValueType));
        InitCommand();
    }
    // Serialization
    public void GetObjectData(SerializationInfo info, StreamingContext ctxt) {
        info.AddValue("Whatever", m_Value);
    }
}
