Definition

Calculates the number of bytes in unmanaged memory that are required to hold the parameters for the specified method.

public:
 static int NumParamBytes(System::Reflection::MethodInfo ^ m);
public static int NumParamBytes (System.Reflection.MethodInfo m);
[System.Security.SecurityCritical]
public static int NumParamBytes (System.Reflection.MethodInfo m);
static member NumParamBytes : System.Reflection.MethodInfo -> int
[<System.Security.SecurityCritical>]
static member NumParamBytes : System.Reflection.MethodInfo -> int
Public Shared Function NumParamBytes (m As MethodInfo) As Integer

Parameters

m
MethodInfo

The method to be checked.

Returns

The number of bytes required to represent the method parameters in unmanaged memory.

Attributes

Exceptions

The m parameter is null.

The m parameter is not a MethodInfo object.

Remarks

The NumParamBytes method returns the stack size (in bytes) needed to represent the parameters of a method signature in unmanaged memory.

Note that the return value of this method is platform-dependent. For example, a signature with a single integer parameter returns a value of 4 on 32-bit platforms and a value of 8 on 64-bit platforms.
