Develop a C# windows form application that allows users to do all of the following:
Import a text from a text file (*.txt).The input file is selected from an open file dialog.
Successfully imported text is displayed on a text box.
Analyze a selected character.

For example the selected char is # :
is Digit :False
is letter :False
is letter or Digit :False
is lower :False
is upper :False
is punctuation :True
is symbol :False

then :
Calculate number of lines in the imported text.
Calculate number of words in the imported text.
Calculate number of letters in the imported text.
Calculate number of digits in the imported text.
Calculate number of uppers in the imported text.
Replace a selected word by anything else.

What you need something like (you need to work at your end to make it work I am just providing bit and pieces - 

        StreamReader reader;
        reader = new StreamReader(@"C:\Users\Documents\data.txt");
        do
        {
            ch = (char)reader.Read();
            /* ... 
                Now you got the char and task is to find out following -
                is digit - use Char.IsDigit(ch) 
                is Letter - use Char.IsLetter(ch)
                is Punctuation - use Char.IsPunctuation(ch) 
                is Symbol - use Char.IsSymbol(ch)  
             */
        } while (!reader.EndOfStream);

Now rest is your homework to complete the program from the given hints :)

this code about Using lists to store data in and retrieve data from.,and Using LINQ to query an array in c#

Develop a C# Windows Form Application that allows users to do all of the following.
Read a List of patient's information from a text file (*.txt), the input text file is selected from the Open File Dialog.
Your program should accept any text file with the following format:
a. The file contains columns with Basic information about patients.
b. Columns may be separated by spaces and/or tabs.
c. The first line in the file is the column header.
d. After the header, each line represents a Patient (name, address, phone#, Bdate, gander ,wheight, height and blood type).
e. Successfully imported patients are displayed on a data grid view in a second form and added to a patient list.

  1. The user will be able to display on The Grid view :
    a) Female patients.
    b) Patients with age<45 year. c) Save Over weighted patients on a text file .  Note: To find over weighted patients you have to calculate the BMI value. BMI=Weight/ (Height*Height). If BMI <18.5 >>>>> under weighted.
    18.5<=BMI<=25 >>>>>>>Normal.
    BMI>25 >>>>>>>>>>>> Over Weighted.
