stringbuilder

I've seen on this site a StringBuilder code sample illustrating AppendFormat usage: using System; using System.Text; class Program { static int[] _v = new int[] { 1, 4, 6 }; static void Main() { StringBuilder b = new StringBuilder(); foreach (int v in _v) { b.AppendFormat("int: {0:0.0}{1}", v, Environment.NewLine); } Console.WriteLine(b.ToString()); } } === Output of the program === int: 1.0 int: 4.0 int: 6.0 Where can I find documentation on those advanced rules for string formatting? Composite Formatting Standard Numeric Format Strings Custom Numeric Format Strings Standard Date and Time

The situation is that I am making a WCF call to a remote server which is returns an XML document as a string. Most of the time this return value is a few K, sometimes a few dozen K, very occasionally a few hundred K, but very rarely it could be several megabytes (first problem is that there is no way for me to know). It's these rare occasions that are causing grief. I get a stack trace that starts: System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown. at System.Xml.BufferBuilder.AddBuffer() at System.Xml.BufferBuilder.AppendHelper(Char* pSource, Int32 count)

对于Java Socket编程而言，有两个概念，一个是ServerSocket，一个是Socket。服务端和客户端之间通过Socket建立连接，之后它们就可以进行通信了。首先ServerSocket将在服务端监听某个端口，当发现客户端有Socket来试图连接它时，它会accept该Socket的连接请求，同时在服务端建立一个对应的Socket与之进行通信。这样就有两个Socket了，客户端和服务端各一个。 对于Socket之间的通信其实很简单，服务端往Socket的输出流里面写东西，客户端就可以通过Socket的输入流读取对应的内容。Socket与Socket之间是双向连通的，所以客户端也可以往对应的Socket输出流里面写东西，然后服务端对应的Socket的输入流就可以读出对应的内容。下面来看一些服务端与客户端通信的例子： 1、客户端写服务端读 服务端代码 public class Server { public static void main(String args[]) throws IOException { //为了简单起见，所有的异常信息都往外抛 int port = 8899; //定义一个ServerSocket监听在端口8899上 ServerSocket server = new ServerSocket(port); /

If I am building a string using a StringBuilder object in a method, would it make sense to: Return the StringBuilder object, and let the calling code call ToString()? return sb; OR Return the string by calling ToString() myself. return sb.ToString(); I guess it make a difference if we're returning small, or large strings. What would be appropriate in each case? Thanks in advance. Edit: I don't plan on further modifying the string in the calling code, but good point Colin Burnett. Mainly, is it more efficient to return the StringBuilder object, or the string? Would a reference to the string get

What is an efficient way to trim whitespace from the end of a StringBuilder without calling ToString().Trim() and back to a new SB new StringBuilder(sb.ToString().Trim()) . Nicholas Petersen The following is an extension method, so you can call it like this: sb.TrimEnd(); Also, it returns the SB instance, allowing you to chain other calls ( sb.TrimEnd().AppendLine() ). public static StringBuilder TrimEnd(this StringBuilder sb) { if (sb == null || sb.Length == 0) return sb; int i = sb.Length - 1; for (; i >= 0; i--) if (!char.IsWhiteSpace(sb[i])) break; if (i < sb.Length - 1) sb.Length = i + 1;
