That's not the minimum value. He said it was the smallest, meaning that you can move the decimal to the LEFT 45 places, not right. Which, if you did this:
float x = 0.000000000000000000000000000000000000000000001F;
Console.WriteLine("Smallest : " + x);
results in Smallest : 1.401298E-45, or approximately 1.5*10^(-45).

How to make generic list at runtime out of this example:
<br />
Assembly asm = Assembly.LoadFile(@"C:\MyDll.dll");<br />
Type myType = asm.GetType("WindowsApplication4.Class1");<br />
Now i dont know how to create generic List<t> from myType any idea?
With no reflection it would be like List<class1> lista = new List<class1>(), but how to make it with reflection?
Thanks.

You just specify the type between the angle brackets:
List<myType> lista = new List<myType>();
Now you have a list of myType objects.

You can`t do that !

Error 1 The type or namespace name 'myType' could not be found (are you missing a using directive or an assembly reference?) D:\Documents and Settings\IvanM\My Documents\Visual Studio 2005\Projects\WindowsApplication4\WindowsApplication4\Form1.cs 24 18 WindowsApplication4<br />

He meant how to create List<mytype> during runtime
|
|
|
|
|
I see.
Why would anyone want to do that? Why not just using a List<object>?
Better yet, why not make an interface that the class can implement, so that you can create a list of that interface, and don't have to use reflection for anything that has to do with the objects.

You can do it like this:
<br />
Assembly asm = Assembly.LoadFile(@"C:\MyDll.dll");<br />
Type myType = asm.GetType("WindowsApplication4.Class1");<br />
<br />
Type ListType = typeof(List<>);<br />
Type ListOfMyType = ListType.MakeGenericType(myType);<br />

Thanks Giorgi,
only one question remains how to add objects to ListOfMyType? Thanks alot!
|
|
|
|

First you will need to create instance of ListOfMyType. You can do it like this:
<br />
object myObject = Activator.CreateInstance(ListOfMyType);<br />
Then use InvokeMember method of Type class to invoke any method of ListOfMyType class. Here is an example from MSDN: Type.InvokeMember Method[^]
|
|
|
|
|
I think that you can`t invoke Add member
Code:
<br />
myObject.GetType().InvokeMember("Add", BindingFlags.Public | BindingFlags.InvokeMethod, null, myObject, new object[] { myType1 } );<br />
Error:
<br />
Method 'System.Collections.Generic.List`1[[MojDll.Class1, MojDll, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]].Add' not found.<br />
|
|
|
|
|
I think it should look like this:
<br />
ListOfMyType.InvokeMember("Add", BindingFlags.Public | BindingFlags.InvokeMethod, null, myObject, new object[] { myType1 } );<br />
|
|

Ah didn`t created instance of class .... everything works now thanks !

public VersionC(float Version)
{
version = Version;
}
}
//code end...
is this using boxing and unboxing?
if it does then how can I convert this code to generic one?
I'm trying hard but the concept is so difficult to me.
please help me.
thanks.

No. VersionC is a class. Only structs cause boxing and unboxing.

If you are using .NET 2.0 you should look at the Collection classes and then return a ReadOnlyCollection rather than copy arrays around. It might improve your design.
