Hi,

I am reading a text file using streamreader.

I want to split the text of file into string of arrays or any collection.

e.g.

Student: Prasad,
xyz
abc
some text here about Prasad.
Student: Raj
abc
ijk
some text here about Raj
Student: Shaan
xxx
some text here about Shaan

Now...

I want the string array as below

C#

array[0] ="Student: Prasad,
xyz
abc
some text here about Prasad."

array[1] ="Student: Raj
abc
ijk
some text here about Raj"

array[2]="Student: Shaan
xxx
some text here about Shaan
"

In above e.g. Student: is my keyword.

[no name] 25-Feb-15 6:14am

take a look at String.Split(..)

That didn't work..

[no name] 25-Feb-15 6:19am

Why not?

Each time the input text contains the keyword, you add a new entry to your array, and then fill it with the following lines of text. If you show the code you have tried and explain what does not work, then we can try to help you.

Either use String.Split:

C#

string inp = File.ReadAllText(@"D:\Temp\xxx.txt");
string[] sections = inp.Split(new string[] {"Student: "},StringSplitOptions.RemoveEmptyEntries);

Or a regex:

C#

string inp = File.ReadAllText(@"D:\Temp\xxx.txt");
string[] sections = Regex.Split(inp, "Student: ",);
