示例1: VisitObjectCreateExpression
public override void VisitObjectCreateExpression (ObjectCreateExpression objectCreateExpression)
{
base.VisitObjectCreateExpression (objectCreateExpression);
var td = GetTypeDef (objectCreateExpression.Type);
if (td == null || !IsDelegate (td) || objectCreateExpression.Arguments.Count != 1)
return;
var a = objectCreateExpression.Arguments.First ();
a.Remove ();
objectCreateExpression.ReplaceWith (a);
}示例2: HandleAnonymousMethod
bool HandleAnonymousMethod(ObjectCreateExpression objectCreateExpression, Expression target, MethodReference methodRef)
{
// Anonymous methods are defined in the same assembly, so there's no need to Resolve().
MethodDefinition method = methodRef as MethodDefinition;
if (method == null || !method.Name.StartsWith("<", StringComparison.Ordinal))
return false;
if (!(method.IsCompilerGenerated() || IsPotentialClosure(method.DeclaringType)))
return false;
// Decompile the anonymous method:
DecompilerContext subContext = context.Clone();
subContext.CurrentMethod = method;
BlockStatement body = AstMethodBodyBuilder.CreateMethodBody(method, subContext);
TransformationPipeline.RunTransformationsUntil(body, v => v is DelegateConstruction, subContext);

AnonymousMethodExpression ame = new AnonymousMethodExpression();
bool isLambda = false;
if (method.Parameters.All(p => string.IsNullOrEmpty(p.Name))) {

if (ame.Parameters.All(p => p.ParameterModifier == ParameterModifier.None)) {
isLambda = (body.Statements.Count == 1 && body.Statements.Single() is ReturnStatement);
}
}
// Replace all occurrences of 'this' in the method body with the delegate's target:
foreach (AstNode node in body.Descendants) {
if (node is ThisReferenceExpression)
node.ReplaceWith(target.Clone());
}
if (isLambda) {
LambdaExpression lambda = new LambdaExpression();
