Provides a set of static methods and properties that provide support for compilers. This class cannot be inherited.
Assembly: mscorlib (in mscorlib.dll)
Thetype exposes the following members.
|EnsureSufficientExecutionStack||Ensures that the remaining stack space is large enough to execute the average .NET Framework function.|
|Equals(Object, Object)||Determines whether the specified Object instances are considered equal.|
|ExecuteCodeWithGuaranteedCleanup||Executes code using a Delegate while using another Delegate to execute additional code in case of an exception.|
|GetHashCode(Object)||Serves as a hash function for a particular object, and is suitable for use in algorithms and data structures that use hash codes, such as a hash table.|
|GetObjectValue||Boxes a value type.|
|InitializeArray||Provides a fast way to initialize an array from data that is stored in a module.|
|PrepareConstrainedRegions||Designates a body of code as a constrained execution region (CER).|
|PrepareConstrainedRegionsNoOP||Designates a body of code as a constrained execution region (CER) without performing any probing.|
|PrepareContractedDelegate||Provides a way for applications to dynamically prepare AppDomain event delegates.|
|PrepareDelegate||Indicates that the specified delegate should be prepared for inclusion in a constrained execution region (CER).|
|PrepareMethod(RuntimeMethodHandle)||Prepares a method for inclusion in a constrained execution region (CER).|
|PrepareMethod(RuntimeMethodHandle, RuntimeTypeHandle())||Prepares a method for inclusion in a constrained execution region (CER) with the specified instantiation.|
|ProbeForSufficientStack||Probes for a certain amount of stack space to ensure that a stack overflow cannot happen within a subsequent block of code (assuming that your code uses only a finite and moderate amount of stack space). We recommend that you use a constrained execution region (CER) instead of this method.|
|RunClassConstructor||Runs a specified class constructor method.|
|RunModuleConstructor||Runs a specified module constructor method.|
The following example shows how to reliably set handles by using the PrepareConstrainedRegions method. To reliably set a handle to a specified pre-existing handle, you must ensure that the allocation of the native handle and the subsequent recording of that handle within a SafeHandle object is atomic. Any failure between these operations (such as a thread abort or out-of-memory exception) will result in the native handle being leaked. You can use the PrepareConstrainedRegions method to make sure that the handle is not leaked.
<StructLayout(LayoutKind.Sequential)> _ Structure MyStruct Public m_outputHandle As IntPtr End Structure 'MyStruct NotInheritable Class MySafeHandle Inherits SafeHandle ' Called by P/Invoke when returning SafeHandles Public Sub New() MyBase.New(IntPtr.Zero, True) End Sub Public Function AllocateHandle() As MySafeHandle ' Allocate SafeHandle first to avoid failure later. Dim sh As New MySafeHandle() RuntimeHelpers.PrepareConstrainedRegions() Try Finally Dim myStruct As New MyStruct() NativeAllocateHandle(myStruct) sh.SetHandle(myStruct.m_outputHandle) End Try Return sh End Function
