Dear All,
I want to convert number string entered in a textbox into integer array, and later on getting alphabet according index value of character array, and value of integer array.
Although, by using lambda expression, I can easily achieve that. But I want to achieve the same without lambda expression, and alternative regular expression for the same.
Note:- In given below code, without lambda expression, if I enter "0AB12", then it will print AABBC, instead of I want to ignore alphabet, and just want to decode in integer. While with lambda expression, it gives me perfect answer- ABC
Please help, it was asked me in a recent interview as a fresher.
protected void btn_Decode_Click(object sender, EventArgs e)
{
char[] arr = new char[] {'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z' };
string result = string.Empty;
var myString = txt_Number.Text;
int myInt;
int[] num_arr = new int[myString.Length];
for (int i = 0; i <myString.Length; i++)
{
if (int.TryParse(myString.Substring(i,1),out myInt))
{
num_arr[i] = int.Parse(myString.Substring(i, 1));
}
}
for (int i = 0; i < num_arr.Length; i++)
{
result = result + arr[num_arr[i]];
}
Response.Write(result);
}
What I have tried:
protected void btn_Decode_Click(object sender, EventArgs e)
{
char[] arr = new char[] {'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z' };
string result = string.Empty;
var myString = txt_Number.Text;
int myInt;
int[] num_arr = new int[myString.Length];
for (int i = 0; i <myString.Length; i++)
{
if (int.TryParse(myString.Substring(i,1),out myInt))
{
num_arr[i] = int.Parse(myString.Substring(i, 1));
}
}
for (int i = 0; i < num_arr.Length; i++)
{
result = result + arr[num_arr[i]];
}
Response.Write(result);
}
