Comment on C# Convert String to Stream, and Stream to String by timm

@krishna: Use the Join method on the String class. For example, to join the array of strings with a newline between each string:

int count = 100;
string[] strings = new string[count]
for (int i = 0; i < count; i++)
strings[i] = i.ToString();
string joined = String.Join( "\n", strings );

Comment on C# Universal Type Converter by Jonny

Interesting, but I'm not sure how useful it is. Just imagine having to remember the type of each property – a nightmare if used in a larger application. What's worse, if you should get a type wrong somewhere there's no exception thrown, instead a default value is returned. Looks suspiciously like an anti-pattern to me.

@Jovit, here's a code snippet that may do what you want. You'll need to add error-handling, check to ensure the input files are the same length, strip any whitespace, etc. This also wouldn't be the best approach for very large files, but hopefully you get the idea.

string[] lines1 = File.ReadAllLines( "file1.txt" );
string[] lines2 = File.ReadAllLines( "file2.txt" );
string[] lines3 = File.ReadAllLines( "file3.txt" );
StringBuilder sb = new StringBuilder();
int count = lines1.Length;
for (int i = 0; i < count; i++)
{
string line = String.Format( "{0} , {1} , {2}", lines1[i], lines2[i], lines3[i] );
sb.AppendLine( line );
}
File.WriteAllText( "output.txt", sb.ToString() );

Comment on Constructor Chaining by Announcing: TinyIoC – An Easy to Use, Hassle Free, Inversion of Control Container | GrumpyDev

[...] Whenever I start a new “pet” project I usually *want* to use IoC, but I don’t really want the hassle of taking a dependency on a container, or adding another binary to my project. Usually this leaves me using “poor man’s IoC”, whereby I define dependencies in my constructors, but I pass them in manually or construct them using constructor chaining. [...]

This is true in the United States, in crappy thrid world countries like Puerto Rico the salary scale is:

$25,000 – $35,000

25K for entry levels (college graduates with less than 5 years of experience)
30 – 35K for people with over 5 years of experience.

About 35K to 40K (extremely lucky case) is what you can expect.

Comment on Console Output from a WinForms Application by Ray

Just an FYI, this may not be a huge concern, I've noticed that when ran from a batch file, this solution works well which was the point of me adding cmd line functionality, so I'm happy, although obviously I still want "perfect"
