Left, Right and Mid

[A.M]

Hi,

Using C#, what is the equivalent of functions Left, Right and Mid that we
had in vb6?

Thanks,
Alan

left is MyString.SubString(0,length)
mid is MyString.SubString(start, length)
right is MyString.SubString(MyString.Length - length)

as well as the answers the other guys have provided, you can also import the
visualbasic lib and actually use left, right and mid in c'

string myString = "My String";
Left: myString.Substring(0, 4); // Left 4 characters
Right: myString.Substring(myString.Length - 4); // Right 4 characters
Mid: myString.Substring(startIndex); // Mid overload 1
Mid: myString.Substring(startIndex, count); // Mid overload 2

Mid has optional parameters, so these act as overloads in C#. The Substring
method can easily handle all formats of the VB methods. You will have to
convert
from using 1 based indexing to 0 based indexing, since the VB functions use 1 to
denote the first character and Substring uses 0.

Thaks John, That is actually a good idea!

No, it's not. Substring is a perfectly good alternative, and one which
stays within the idiom of C# and .NET, rather than making your code
look like a mixture of C# and old VB.

It will work, but it will be harder for other C# programmers (without
VB experience) to understand. It will require the Microsoft.VisualBasic
assembly to be loaded for no particularly good reason. It will use a
method which has been significantly less thoroughly tested than
Substring (because virtually all .NET programmers use Substring whereas
only a few will be using the ported VB methods).

Remember that in .NET strings are objects. So dont look for global functions,
but look at the methods of the string object itself.

I couldn't agree more. Just because something can be done
is not a logical reason for doing so.

Thank you for comment.

Unfotunately, I have to be 100% agree with you about about using
Microsoft.VisualBasic assmebly; however I have to subclass my own simple
string class to abstract Left and Mid and Right. It is not the name of
function. It is more convenient to send a simple parameter which is really
needed for that operation if we use it too often.

I was excited because I didn't think about using Microsoft.VisualBasic
assmebly in C# !

Thank you again,
Alan
