The content type is a header of the content, not of the request, which is why this is failing. AddWithoutValidation as suggested by Robert Levy may work, but you can also set the content type when creating the request content itself (note that the code snippet adds application/json in two places-for Accept and Content-Type headers): … Read more
It really depends on whether or not you can trust s.Length. For many streams, you just don’t know how much data there will be. In such cases – and before .NET 4 – I’d use code like this: public static byte[] ReadFully(Stream input) { byte[] buffer = new byte[16*1024]; using (MemoryStream ms = new MemoryStream()) … Read more
Shuffle any (I)List with an extension method based on the Fisher-Yates shuffle: private static Random rng = new Random(); public static void Shuffle<T>(this IList<T> list) { int n = list.Count; while (n > 1) { n–; int k = rng.Next(n + 1); T value = list[k]; list[k] = list[n]; list[n] = value; } } Usage: … Read more
When you want to treat lambda expressions as expression trees and look inside them instead of executing them. For example, LINQ to SQL gets the expression and converts it to the equivalent SQL statement and submits it to server (rather than executing the lambda). Conceptually, Expression<Func<T>> is completely different from Func<T>. Func<T> denotes a delegate … Read more
System.Reflection.Assembly.GetExecutingAssembly().Location1 Combine that with System.IO.Path.GetDirectoryName if all you want is the directory. 1As per Mr.Mindor’s comment: System.Reflection.Assembly.GetExecutingAssembly().Location returns where the executing assembly is currently located, which may or may not be where the assembly is located when not executing. In the case of shadow copying assemblies, you will get a path in a temp directory. … Read more
string result = System.Text.Encoding.UTF8.GetString(byteArray);
What’s likely happening is that SignalData is indirectly changing the subscribers dictionary under the hood during the loop and leading to that message. You can verify this by changing foreach(Subscriber s in subscribers.Values) To foreach(Subscriber s in subscribers.Values.ToList()) If I’m right, the problem will disappear. Calling subscribers.Values.ToList() copies the values of subscribers.Values to a separate … Read more
public static object GetPropValue(object src, string propName) { return src.GetType().GetProperty(propName).GetValue(src, null); } Of course, you will want to add validation and whatnot, but that is the gist of it.
You can’t query against the DataTable‘s Rows collection, since DataRowCollection doesn’t implement IEnumerable<T>. You need to use the AsEnumerable() extension for DataTable. Like so: var results = from myRow in myDataTable.AsEnumerable() where myRow.Field<int>(“RowNo”) == 1 select myRow; And as @Keith says, you’ll need to add a reference to System.Data.DataSetExtensions AsEnumerable() returns IEnumerable<DataRow>. If you need … Read more
For you to output foo {1, 2, 3} you have to do something like: string t = “1, 2, 3″; string v = String.Format(” foo {{{0}}}”, t); To output a { you use {{ and to output a } you use }}. Or now, you can also use C# string interpolation like this (a feature … Read more
