Import .srt file to datagrid

Question

Hi,

 

This has been driving me mad all week, so finally I gave in an am posting for some help. I am a budding c# programmer and have made lots of simple programs. Every time I decide to try something new, something crops up that I can't yet solve.

 

I am trying to make an editor for syncing srt subtitle files. I can load the subtitle file, I can send it to a textbox if i want to, i can trim and split the time line and send them to different places, but I am having difficulty processing it as a whole.

 

I practiced splitting and trimming the time line when i had the text string in a textbox just to make it simple.

 

The srt file is structured like:

 

1

00:00:01,151 --> 00:00:03,432

Subtitle Line 1

2

00:00:05,651 --> 00:00:07,238

Subtitle Line 1 sub 2

Subtitle Line 2 sub 2

3

00:00:08,751 --> 00:00:10,065

Subtitle Line 1 sub 3

etc etc etc 

 

I placed the "00:00:01,151 --> 00:00:03,432" line in textBox1 and using the code:

 

(sorry couldn't find the code tags)

 

//splits the string and keeps the text before the -->

string startTime = textBox1.Text;

string result = startTime.Substring(0, theString.IndexOf("-->")).Trim();

textBox4.Text = result;

//takes the text after the delimiter

int index = textBox1.Text.IndexOf('>');

string result2 = textBox1.Text.Substring(index + 2); 

textBox5.Text = result2;

This code puts each part into separate text boxes and works as i want.

 

I have a good handle on logic code and can understand what i need to do, but not how to do it.

 

- I need to read the line and if it contains only an integer, send it to column 1.

-I need to read the line and if it contains '-->' use the above code or similar and send it to cols 2 and 3.

- i need to read the next line and send it to col 4 (1st subtitle text line, will always contain text) 

- i need to read the line and if it is blank, make a new row, else append the text to the text in column 4 and then make new row. Then start over.

 

Logically, i know what to do, but i am having trouble with looping through and processing each line.

 

Does anyone have any tips that could help me please? Thanks
