摘要： In my previous entry on IL modification we looked at the details for inserting a method call with a known (hardcoded) method token. We also used metadata to list the available methods, as a way to avoid this hardcoding. When listing the methods on a given class, the method signatures were available, but we didn't use them. In this short entry, we'll extend our metadata inspection a little bit by using an existing method's signature to search for another method with a matching signature. 阅读全文

摘要： We'll insert a method call at the beginning of the body of the Main method. The method we'll call is as easy as can be: it is part of the of the same class, is static and has a void() signature. The IL used during the modification is still hardcoded. But we'll try to start moving away from that by exploring the metadata, to try and find the method token at runtime. The first step of this is to list all the methods on the current class and print out their names, which we'll see how to do 阅读全文
