streamwriter

I'm creating a method to serialize a file using this code: public void Save(Object file, Type type, String path) { // Create a new Serializer XmlSerializer serializer = new XmlSerializer(typeof(type)); // Create a new StreamWriter StreamWriter writer = new StreamWriter(@path); // Serialize the file serializer.Serialize(writer, file); // Close the writer writer.Close(); } But Visual Studio tells me this when I attempt to build: "Error 1 The type or namespace name 'type' could not be found (are you missing a using directive or an assembly reference?) c:\users\erik\documents\visual studio 2013

in my Wpf app I'm using a class Person (that is a base class), and that contains a virtual method SaveData(), and other class Client that inherits from Person. How to override method SaveData() and keeping data from base? Class Person public virtual void SaveData() { string arqName = string.Format("Person{0}" + ".txt", Id); StreamWriter file = new StreamWriter(arqNome); file.WriteLine("ID: " + Id); file.WriteLine("DOB: " + dOB); file.WriteLine("Name: " + name); file.WriteLine("Age: " + age); file.Flush(); file.Close(); } Class Client public override void SaveData() { base.SaveData(); string

using (var writer = File.CreateText(fullFilePath)) { file.Write(fileContent); } Given the above code, can the file size be known from StreamWriter ? Yes, you can, try the following long length = writer.BaseStream.Length;//will give unexpected output if autoflush is false and write has been called just before Note: writer.BaseStream.Length property can return unexpected results since StreamWriter doesn't write immediately. It caches so to get expected output you need AutoFlush = true writer.AutoFlush = true; or writer.Flush(); long length = writer.BaseStream.Length;//will give expected output I

Okay so my program has around 30 threads, and I need to make a log of some of the information gathered through each threads. The way I did this is by: Creating a public static StringBuilder in the class Program, and then each thread will call the AppendLine method to this StringBuilder instance every few minutes. Then, every 30 minutes another Thread dedicated to writing using a StreamWriter does exactly that. For example: public class Program { public static StringBuilder sb = new StringBuilder(); public static void Main(string[] args) { // Start all threads } } public class Example { Thread

I'm trying to check to see if a file exists, if so it does nothing. If the file does not exist is creates the text file. Then I want to write text to that file. Where am I going wrong with this code? I'm just trying to write multiple lines to the text file and that part is not working. It is creating the text file... just not writing to it. Dim file As System.IO.FileStream Try ' Indicate whether the text file exists If My.Computer.FileSystem.FileExists("c:\directory\textfile.txt") Then Return End If ' Try to create the text file with all the info in it file = System.IO.File.Create("c:
