Hi friends,

I have a file that contains lines like this ...

Delphi

app_title_data = "This is the title of the application"
app_subtitle_data = "This is the subtitle"
; Comment goes here
app_content ="Content goes here"

I could retrieve the entire line using file reader...
I want to get the string inside double quotes for the specific keyword,,,
But I dont want to loop for each character,,, since the file may be very large...
Now I am using this code to split the keyword and value...

C#

string[] str = line.Trim().Split(new string[] { "=" }, StringSplitOptions.None);

Any suggestions ??

Solution 1

Do one thing concantanate each line of a string inside the loop while when reading the file using reader. from that result you can use the split function

C#

result.Split(new string[] { "=" }, StringSplitOptions.None);

Hope this helps

private static string GetActualValuefromText(string curval)
{
int fi = curval.IndexOf("\"", StringComparison.Ordinal);
if (fi != -1)
{
int la = curval.IndexOf("\"", fi + 1, StringComparison.Ordinal);
if (la != -1)
return curval.Substring(fi + 1, la - (fi + 1));
}
return "";
}
