◆ CurrentThreadRequiresSecurityContextCapture()

static bool System.Security.SecurityManager.CurrentThreadRequiresSecurityContextCapture ( )

static

Determines whether the current thread requires a security context capture if its security state has to be re-created at a later point in time.

Returns: false if the stack contains no partially trusted application domains, no partially trusted assemblies, and no currently active M:System.Security.CodeAccessPermission.PermitOnly or M:System.Security.CodeAccessPermission.Deny modifiers; true if the common language runtime cannot guarantee that the stack contains none of these.

static

Gets a permission set that is safe to grant to an application that has the provided evidence.

Parameters

evidence The host evidence to match to a permission set.

Returns: A permission set that can be used as a grant set for the application that has the provided evidence.

Exceptions

T:System.ArgumentNullException evidence is null.
