Title Body

I am getting this error on a routine which uses reflection to dump some object properties, something like the code below. MemberInfo[] members = obj.GetType().GetMembers(BindingFlags.Public | BindingFlags.Instance) ; foreach (MemberInfo m in members) { PropertyInfo p = m as PropertyInfo; if (p != null) { object po = p.GetValue(obj, null); ... } } The actual error is "Exception has been thrown by the target of an invocation" with an inner exception of "Method may only be called on a Type for which Type.IsGenericParameter is true." At this stage in the debugger obj appears as {Name = "SqlConnection" FullName = "System.Data.SqlClient.SqlConnection"} with the type System.RuntimeType The method m is {System.Reflection.MethodBase DeclaringMethod} Note that obj is of type System.RuntimeType and members contains 188 items whereas a simple typeof(System.Data.SqlClient.SqlConnection).GetMembers(System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance) only returns 65. I tried checking isGenericParameter on both obj and p.PropertyType, but this seems to be false for most properties including those where p.GetValue works. So what exactly is a "Type for which Type.IsGenericParameter is true" and more importantly how do I avoid this error without a try/catch?
