Impl Options Enum
Specifies constants that define the details of how a method is implemented.
This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.
public enum class MethodImplOptions
public enum MethodImplOptions
[System.Flags] public enum MethodImplOptions
[System.Flags] [System.Serializable] public enum MethodImplOptions
[System.Flags] [System.Serializable] [System.Runtime.InteropServices.ComVisible(true)] public enum MethodImplOptions
type MethodImplOptions =
[<System.Flags>] type MethodImplOptions =
[<System.Flags>] [<System.Serializable>] type MethodImplOptions =
[<System.Flags>] [<System.Serializable>] [<System.Runtime.InteropServices.ComVisible(true)>] type MethodImplOptions =
Public Enum MethodImplOptions
The method should be inlined if possible.
The method contains a hot path and should be optimized.
The method is declared, but its implementation is provided elsewhere.
The call is internal, that is, it calls a method that's implemented within the common language runtime.
The method cannot be inlined. Inlining is an optimization by which a method call is replaced with the method body.
The method is not optimized by the just-in-time (JIT) compiler or by native code generation (see Ngen.exe) when debugging possible code generation problems.
The method signature is exported exactly as declared.
This member is reserved for future use. It was introduced in .NET Framework 4.8.
The method can be executed by only one thread at a time. Static methods lock on the type, whereas instance methods lock on the instance. Only one thread can execute in any of the instance functions, and only one thread can execute in any of a class's static functions.
The method is implemented in unmanaged code.
This enumeration is used with the MethodImplAttribute attribute.
You can specify multiple MethodImplOptions values by using the bitwise OR operator.
Locking on the instance or on the type, as with the
Synchronized flag, is not recommended for public types, because code other than your own can take locks on public types and instances. This might cause deadlocks or other synchronization problems.
