rank är inte ett giltigt antal dimensioner. Till exempel är dess värde mindre än 1.

Exempel

I följande kodexempel skapas en dynamisk modul, en abstrakt allmän typ med namnet Sample med en typparameter och Ten abstrakt metod med namnet TestMethod. TestMethod tar en parameter ref (ByRef i Visual Basic) av typen T, en pekare för att skriva T och en matris med T. Den här metoden returnerar en tvådimensionell matris med T. Kodexemplet sparar den dynamiska modulen på disken, så att du kan undersöka den med hjälp av MSIL Disassembler (Ildasm.exe).
