Programming in C#

Please help me with these two programs

1. Write a console app called CountLowers that lets a user enter characters until the user types a right brace character '}'. As each character is entered, determine whether it is a lowercase letter. If it is lowercase, count it. When the user has finished entering characters, display the number of lowercase letters as well as the number of other characters entered. Note that the right brace character should not be counted (it's used as a sentinel value). Turn in output showing the input of several lowercase and "other" characters.

2. Write a console app called Sum125 that sums all the integers from 1 to 125. Use a loop and an accumulator (not a formula) to make the calculation. Display the total when the loop finishes.
