C# – The type or namespace name ‘FileIO’ does not exist in the namespace ‘Microsoft.VisualBasic’

asp.netcvisual studio

I am using visual studio 2012 and .Net framework 4.5. I have included 'Microsoft.VisualBasic' in my project reference.

I am getting the following error while executing the project.

Compilation Error Description: An error occurred during the
compilation of a resource required to service this request. Please
review the following specific error details and modify your source
code appropriately.

Compiler Error Message: CS0234: The type or namespace name 'FileIO'
does not exist in the namespace 'Microsoft.VisualBasic' (are you
missing an assembly reference?)

Source Error:

      int lineNumber = 0;
      int flag = 1;
     using (Microsoft.VisualBasic.FileIO.TextFieldParser parser = new Microsoft.VisualBasic.FileIO.TextFieldParser(file))
     {
        parser.CommentTokens = new string[] { "#" };

I had tried adding the reference again and again but it doesn't seems to be working.

I even tried the answers from following question in Stack Overflow but nothing helped
microsoft.visualbasic.fileio does not exist

here is my reference and properties of Microsoft visual basic

Please help me

I got this problem solved now

I have copied Microsoft.VisualBasic.dll file to the bin folder of my project and now it seems to be working fine. (OR) You can change the Properties of the reference as follows

right click the Microsoft.VisualBasic reference in solution explorer and change **Copy Local** property value as '**True**'

-> Right click the Microsoft.VisualBasic reference in solution explorer and change Copy Local property value as 'True' . This will do the trick

C# – Should ‘using’ directives be inside or outside the namespace

There is actually a (subtle) difference between the two. Imagine you have the following code in File1.cs:

// File1.cs
using System;
namespace Outer.Inner
{
    class Foo
    {
        static void Bar()
        {
            double d = Math.PI;
        }
    }
}

Now imagine that someone adds another file (File2.cs) to the project that looks like this:

// File2.cs
namespace Outer
{
    class Math
    {
    }
}

The compiler searches Outer before looking at those using directives outside the namespace, so it finds Outer.Math instead of System.Math. Unfortunately (or perhaps fortunately?), Outer.Math has no PI member, so File1 is now broken.

This changes if you put the using inside your namespace declaration, as follows:

// File1b.cs
namespace Outer.Inner
{
    using System;
    class Foo
    {
        static void Bar()
        {
            double d = Math.PI;
        }
    }
}

Now the compiler searches System before searching Outer, finds System.Math, and all is well.

Some would argue that Math might be a bad name for a user-defined class, since there's already one in System; the point here is just that there is a difference, and it affects the maintainability of your code.

It's also interesting to note what happens if Foo is in namespace Outer, rather than Outer.Inner. In that case, adding Outer.Math in File2 breaks File1 regardless of where the using goes. This implies that the compiler searches the innermost enclosing namespace before it looks at any using directive.

C# – The name ‘ConfigurationManager’ does not exist in the current context

It's not only necessary to use the namespace System.Configuration. You have also to add the reference to the assembly System.Configuration.dll , by

Right-click on the References / Dependencies
Choose Add Reference
Find and add System.Configuration.

This will work for sure. Also for the NameValueCollection you have to write:

using System.Collections.Specialized;
