with Reflection API, I want to define a array of some type. if the type is
defined in else assembly, I can get the array type by call Type.GetType(
"TypeName[]" ). but with a type i am defining in same dynamic module, and i
cannot create type before define the array type. then how should i to get
the array type.

Maybe I am confused, You should be able to create a "Array" type use
that to stuff the types. Maybe I am wrong..

you can use the static Method Array.CreateInstance

e.g.:
Array my3DArray=Array.CreateInstance( typeof(Object), 2, 3, 4 );
for ( int i = my3DArray.GetLowerBound(0); i <=
my3DArray.GetUpperBound(0); i++ )
for ( int j = my3DArray.GetLowerBound(1); j <=
my3DArray.GetUpperBound(1); j++ )
for ( int k = my3DArray.GetLowerBound(2); k <=
my3DArray.GetUpperBound(2); k++ )
my3DArray.SetValue( "abc" + i + j + k, i, j, k );

Thanks to you! but I am not to create a instance of array, but to get the
array's type to use in some Emit API.

Have you tried using ModuleBuilder.GetType() instead?

Yes, ModuleBuilder.GetType( ) is what I want!
