示例1: EmitPredefined

		public void EmitPredefined (EmitContext ec, MethodSpec method, Arguments Arguments, bool statement = false, Location? loc = null)
		{
			Expression instance_copy = null;

			if (!HasAwaitArguments && ec.HasSet (BuilderContext.Options.AsyncBody)) {
				HasAwaitArguments = Arguments != null && Arguments.ContainsEmitWithAwait ();
				if (HasAwaitArguments && InstanceExpressionOnStack) {
					throw new NotSupportedException ();
				}
			}

			OpCode call_op;
			LocalTemporary lt = null;

			if (method.IsStatic) {
				call_op = OpCodes.Call;
			} else {
				call_op = IsVirtualCallRequired (InstanceExpression, method) ? OpCodes.Callvirt : OpCodes.Call;

				if (HasAwaitArguments) {
					instance_copy = InstanceExpression.EmitToField (ec);
					var ie = new InstanceEmitter (instance_copy, IsAddressCall (instance_copy, call_op, method.DeclaringType));

					if (Arguments == null) {
						ie.EmitLoad (ec, true);
					}
				} else if (!InstanceExpressionOnStack) {
					var ie = new InstanceEmitter (InstanceExpression, IsAddressCall (InstanceExpression, call_op, method.DeclaringType));
					ie.Emit (ec, ConditionalAccess);

					if (DuplicateArguments) {
						ec.Emit (OpCodes.Dup);

				ec.Emit (OpCodes.Constrained, InstanceExpression.Type);
			}

			if (loc != null) {
				//
				// Emit explicit sequence point for expressions like Foo.Bar () to help debugger to
				// break at right place when LHS expression can be stepped-into
				//
				ec.MarkCallEntry (loc.Value);

			//
			// Set instance expression to actual result expression. When it contains await it can be
			// picked up by caller
			//
			InstanceExpression = instance_copy;

			if (method.Parameters.HasArglist) {
				var varargs_types = GetVarargsTypes (method, Arguments);
				ec.Emit (call_op, method, varargs_types);
			} else {
				//
				// If you have:
				// this.DoFoo ();
				// and DoFoo is not virtual, you can omit the callvirt,
				// because you don't need the null checking behavior.
				//
				ec.Emit (call_op, method);
			}

			// 
			// Pop the return value if there is one and stack should be empty
			//
			if (statement && method.ReturnType.Kind != MemberKind.Void)
				ec.Emit (OpCodes.Pop);
