MethodBody::LocalVariables Property

 

Gets the list of local variables declared in the method body.

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

public:
property IList<LocalVariableInfo^>^ LocalVariables {
	virtual IList<LocalVariableInfo^>^ get();
}

Property Value

Type: System.Collections.Generic::IList<LocalVariableInfo^>^

An IList<T> of LocalVariableInfo objects that describe the local variables declared in the method body.

You do not need the metadata token for the local variable signature provided by the LocalSignatureMetadataToken property.

The following code example defines a test method named MethodBodyExample and displays its local variable information. The MethodBase::GetMethodBody method is used to obtain a MethodBody object for the test method. The LocalVariables property is used to obtain a list of LocalVariableInfo objects.

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

    // the properties and methods of the MethodBody class.

        // the local variable list includes the variables scoped to 
        // the catch clauses.
