MethodBody::MaxStackSize Property

 

Gets the maximum number of items on the operand stack when the method is executing.

Namespace:   System.Reflection
Assembly:  mscorlib (in mscorlib.dll)

public:
property int MaxStackSize {
	virtual int get();
}

Property Value

Type: System::Int32

The maximum number of items on the operand stack when the method is executing.

For more information, see the Common Language Infrastructure (CLI) documentation, especially "Partition II: Metadata Definition and Semantics" and "Partition III: CIL Instruction Set". The documentation is available online; see ECMA C# and Common Language Infrastructure Standards on MSDN and Standard ECMA-335 - Common Language Infrastructure (CLI) on the Ecma International Web site.

The following code example defines a test method named MethodBodyExample and displays its local variable information and exception-handling clauses. The MethodBase::GetMethodBody method is used to obtain a MethodBody object for the test method. The MaxStackSize and InitLocals properties are displayed.

This code example is part of a larger example provided for the MethodBody class.

#using <System.dll>

    // the properties and methods of the MethodBody class.
