extracting code from string

Expand Post »

hey there. thanks for all the help i have recieved from the people on this site!

i have a new problem, one i could solve if i was using VB but im using C# and i dont really know what to do.

i have data....

return1.MV TE244654.MV b43tgwg.sp
01.62 00.83 100.76
01.62 00.83 100.77
01.60 00.83 100.78
--.-- 00.83 100.79
--.-- 00.82 100.80
01.63 00.83 100.81
01.63 00.83 100.82
--.-- 00.83 100.83
--.-- 00.83 100.84
01.62 00.83 100.85
01.59 00.83 100.86
--.-- 00.83 100.88
--.-- 00.83 100.89
01.61 00.84 100.90
01.60 00.84 100.91

basically i need to organise this data into an array, but its more difficult that it seems.

like the array needs to be like this

values[x,y]
values[0,0] = return1.MV
values[0,1] = 01.62
values[0,2] = 01.62
values[1,0] = TE244654.MV
values[1,1] = 00.83

etc etc.

however each row is one big string
eg. " 01.62 00.83 100.26" so i need to separate each part to put into the array.

what would be the code i would use to make this happen in C#. as i said i know what i would need to do, and if i as using VB i could use left right and mid. if you could help that would be amazing.

Re: extracting code from string

You could use the method SubString here like Mystr.SubString(charpos,lenghttoextract);
You can let this work like left,mid,right if you want.

Re: extracting code from string

Like this:

c# Syntax (Toggle Plain Text)
string Mystr = "01.62 00.83 100.76";
string Leftstr = Mystr.Substring(0, 5); // Leftstr is equal to 01.62 
string Midstr = Mystr.Substring(6, 5);  // Midstr00.83
string Rightstr = Mystr.Substring(Mystr.Length - 5, 5);  // Rightstr 00.76
string Mystr = "01.62 00.83 100.76";
string Leftstr = Mystr.Substring(0, 5); // Leftstr is equal to 01.62 
string Midstr = Mystr.Substring(6, 5);  // Midstr00.83
string Rightstr = Mystr.Substring(Mystr.Length - 5, 5);  // Rightstr 00.76

First integer of substring is the zero based char position in the string. The second integer is the length in characters of the string you want to extract.

[edit]Oops, I didn't see Danny already answered it. His answer is probably closer to how you originally went about it, and will probably be easier to implement[/edit]
