binaryformatter

问题 I have a string which is converted in binary format but the binary conversion method removes it leading zero's and I am not sure how much leading zero's I should add in the start .It depends on the string my code is as follows public static void encodeString(String str){ byte[] bytes=str.getBytes(); String binary = new BigInteger(bytes).toString(2); } 回答1: I understand that you are trying to preserve the 8-bits representation of each character of your input String . to do so, I used this

问题 I'm new to object serialization, and in the course of my learning how to read from and write to a file (deserialize and serialize) using BinaryFormatter , I came across BinaryReader and BinaryWriter , which seemed to be doing the same thing. Is there some subtle difference between BinaryFormatter.Serialize() and BinaryWriter ? Or is BinaryWriter just a more compact way performing the the same action as BinaryFormatter.Serialize() ? 回答1: BinaryWriter is used to write primitive types in binary

问题 After searching for an answer to this issue for the last 2 days, I'm hoping someone here can help. I have written a program in c# using VS2012 that saves the user's project data using BinaryFormatter to serialize a serializable class to a Stream before saving it to a file. The programme has been in use for some time, however recently a user couldn't open a file he saved the day before. He sent me the file, and the error I get in the degugger is: "Binary stream '0' does not contain a valid

问题 Using the BinaryFormatter class: <Serializable> Class Class1 Public Property List1 as New List(Of Something) <NonSerialized> Public Property List2 as New List(Of Something) End Class when I serialize an object like this one and then deserialize it, List2 will be set to Nothing . What is the correct way to handle this? I don't want List2 to be serialized, but I do want it to be an empty list when I deserialize the class. 回答1: BinaryFormatter doesn't call a class Constuctor, nor it initializes

问题 I am trying to deserialize a file which is serialized using an older version. In the new version, We have done the following things change namespace Change class member access level, from private to public Add a new inter parent class. Class A was derived from Base. Now, Class A is derived from B, and B is derived from Base. In B, there is no new member introduced. Base class adds a new member. I know using SerializationBinder can solve issue 1. For the new added class member, I have marked

问题 When .NET's BinaryFormatter is used to serialize an object graph, is any type of compression applied? I ask in the context of whether I should worry about the object graph having many repeated strings and integers. Edit - Hold on, if strings are interned in .NET, there's no need to worry about repeated strings, right? 回答1: No, it doesn't provide any compression but you can compress the output yourself using the GZipStream type. Edit: Mehrdad has a wonderful example of this technique in his
