CallConvThiscall Class

Indicates that a method should use the ThisCall calling convention.

Namespace: System.Runtime.CompilerServices
Assembly: mscorlib (in mscorlib.dll)

[ComVisibleAttribute(true)] 
public class CallConvThiscall
/** @attribute ComVisibleAttribute(true) */ 
public class CallConvThiscall
ComVisibleAttribute(true) 
public class CallConvThiscall

When using the ThisCall calling convention, the first parameter of a method call is the this pointer, which is stored in register ECX. Other parameters of a method call are pushed on the stack. This calling convention is used to call methods on classes exported from an unmanaged DLL.

The classes in System.Runtime.CompilerServices are for compiler writers' use only.

Compilers emit custom modifiers within metadata to change the way that the just-in-time (JIT) compiler handles values when the default behavior is not appropriate. When the JIT compiler encounters a custom modifier, it handles the value in the way that the modifier specifies. Compilers can apply custom modifiers to methods, parameters, and return values. The JIT compiler must respond to required modifiers but can ignore optional modifiers. A C++ compiler could emit a custom modifier to describe how a byte should be treated in cases where the JIT compiler treats bytes in a manner that is not compatible with C++ by default.

You can emit custom modifiers into metadata using one of the following techniques:

System.Object
  System.Runtime.CompilerServices.CallConvThiscall
