System.Reflection - how to access and invoke private methods,fields or properties

For demonstration purpose I've created a class that contains only private methods,fields and properties

/// <summary>
/// Holds blog information
/// </summary>
public class Blog
/// <summary>
/// Gets the posts count.
/// </summary>
private static int PostsCount
return 10000;

/// <summary>
/// Gets the description.
/// </summary>
/// <returns></returns>
private string GetDescription()
return @"A weblog dedicated to obsessively profiling
reviewing new Internet products and companies"

/// <summary>
/// Changes the name of the blog.
/// </summary>
/// <param name="newName">The new name.</param>
private string ChangeBlogName(string newName)
name = newName;
return name;

string url = "";
string name = "Tech Crunch";


To access private fields I used the System.Reflection.FieldInfo class .For private properties I used System.Reflection.PropertyInfo .Note if you want to work with private members you should use System.Reflection.BindingFlags enum as shown in the example below .So for non-static class members the flags should looks like BindingFlags.NonPublic | BindingFlags.Instance .For static don't forget to add BindingFlags.Static .

class Program
static void Main(string[] args)

Blog blog = new Blog();
Type type = typeof(Blog);
//create reflection bindings - will be used to retrive private fields,methods or properties
BindingFlags privateBindings = BindingFlags.NonPublic | BindingFlags.Instance;

// retrive private fields from our class
FieldInfo[] fieldInfos = type.GetFields(privateBindings);

// retrive private fields metadata
foreach (FieldInfo fieldInfo in fieldInfos)
Console.WriteLine(fieldInfo.Name +" "+ fieldInfo.GetValue(blog));

PropertyInfo [] propertyInfos = type.GetProperties(privateBindings|BindingFlags.Static);
// retrive private static properties metadata
foreach (PropertyInfo propertyInfo in propertyInfos)
// note that no instance need for static property to retrive it's value
Console.WriteLine(propertyInfo.Name + " " + propertyInfo.GetValue(null,null) );

// call method using MethodInfo object
MethodInfo miGetDescription = type.GetMethod("GetDescription", privateBindings);
object retObj = miGetDescription.Invoke(blog, new object[]{});

// call method using MethodInfo object with input parameters
MethodInfo miChangeBlogName = type.GetMethod("ChangeBlogName", privateBindings);
retObj = miChangeBlogName.Invoke(blog, new object[] { "Yahoo blog" });




The console output fallows

Microsoft® Visual Studio Team System 2008 Database Edition Power Tools

Microsoft Visual Studio Team System 2008 Database Edition Power Tools is a set of enhancements and tools that complement and improve the user experience of VSTS Database Edition 2008

• ChecksumCondition – You can use this test condition to verify that the checksum of the data set returned by a database unit test matches the checksum of an expected data set.
• ExpectedSchemaTestCondition – You can use this test condition to verify that the column names and data types of the returned data set match expected values.
Data Generator Improvements
• New Data Generator Wizard – This new wizard creates a data generation plan that is configured to copy data from a source database. You can use this wizard when you need to copy most of your data from a live source, but need to make small changes to ensure privacy.
MSBuild Task Improvements
• SqlAnalysis Task – You can use this build task to run T-SQL Static Code Analysis from MSBuild.
TSQL Static Code Analysis
• Static Code Analysis - A precursor to the functionality that will be in future versions of VSTS that will allow you to perform Static Code Analysis on T-SQL code.
• “Move Schema” Refactoring - Allows a user to right click on an object and move it to a different but existing schema
• SP Rename Generation - Generate a new script that will contain sp_renames for all rename refactored objects that the user can then execute.
• Wildcard Expansion - Automatically expand the wildcard in a select to the appropriate columns.
• Fully-Qualified Name Support - Automatically inject fully-qualified names when absent in a script
• Refactoring extended to Dataset - Refactor into strongly typed dataset definitions
MSBuild Tasks
• Data / Schema Compare Build Tasks - MSBuild tasks that can generate scripts as if the user had run the Data / Schema compare UI
Schema View
• API Access to Schema View - Insert / Update / Delete to schema View and list schema objects and their associated files
Dependency Tool Window
• Dependency Tree - Show the dependencies ( incoming / outgoing ) for selected schema objects in a new tool window
Miscellaneous Tools
• Script Preprocessor - Expand SQLCMD variables and include files and command line version (sqlspp.exe) & an MSBuild version ( wraps the command line version )

LINQ to Objects - 3 basic examples


The examples below show how you can use aggregate operators in "LINQ to Objects"

// our test data array
string[] names = { "Sara", "Bill", "Alex", "Don", "Tom", "David", "Dana" };

// Find names starts with with character 'D'
int namesStartsWithD = names.Count( name => name.StartsWith("d",
StringComparison.CurrentCultureIgnoreCase ) );
Console.WriteLine("There are {0} names that start with character 'D' in the name list.",

// Find the longest name
int longestName = names.Max( name=>name.Length );
Console.WriteLine("The longest name is {0} characters long.", longestName);

// Find the first name that starts with character 'D'
string firstStartsWithD = names.First(name => name.StartsWith("d",
StringComparison.CurrentCultureIgnoreCase) );
Console.WriteLine("The first name that start with 'D' - {0}.", firstStartsWithD);

SVN-IIS gives access to Subversion via MS IIS
The main goal of this project is to make a direct interface from a SVN repository to WebDav interface running on MS IIS.


  • Practically no overhead
  • Tested on IIS5.x and IIS6.x
  • Tested on http and https (used a test certificate)
  • Support for HTTP 1.1 Chunked encoding
  • Runs on Windows XP\2000\2003\Vista
  • Apache like logging


  • .NET Framework
  • Access from the IIS to a running Apache webserver, interfacing a SVN repository
