ILGenerator.DeclareLocal Method (Type, Boolean)

Declares a local variable of the specified type, optionally pinning the object referred to by the variable.

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

public virtual LocalBuilder DeclareLocal(
	Type localType,
	bool pinned
)

Parameters

localType
Type: System.Type

A Type object that represents the type of the local variable.

pinned
Type: System.Boolean

true to pin the object in memory; otherwise, false.

Return Value

Type: System.Reflection.Emit.LocalBuilder
A LocalBuilder object that represents the local variable.

ExceptionCondition
ArgumentNullException

localType is null.

InvalidOperationException

The containing type has been created by the TypeBuilder.CreateType method.

-or-

The method body of the enclosing method has been created by the MethodBuilder.CreateMethodBody method.

NotSupportedException

The method with which this ILGenerator is associated is not represented by a MethodBuilder.

The local variable is created in the current lexical scope; for example, if code is being emitted in a for loop (For loop in Visual Basic), the scope of the variable is the loop.

In unsafe code, an object must be pinned before it can be referred to by an unmanaged pointer. While the referenced object is pinned, it cannot be moved by garbage collection.
