This question is really not very clear. You have a number of different suggestions, one or more of which may be the solution. Please add some more detail about what problem you are trying to solve.

Solution 3

You can use regular expression to separate string and number.

Regex string to use: (?<string>[A-Za-z]+)(?<number>\d+)

C#

System.Text.RegularExpressions.Match m = System.Text.RegularExpressions.Regex.Match("C001", @"(?<string>[A-Za-z]+)(?<number>\d+)");

if (m.Success)
{
  Console.WriteLine("String is: " + m.Groups["string"].Value + ", Number is: " + m.Groups["number"].Value);
}

This will give you an output:

String is: C, Number is: 001

From her you can do all numeric operations on "number".

Suggestion from yesotaso

Custom build your own class

C#

class myInt
{
  public int Value;
  public static myInt operator +(myInt left,int right)
  {
    return new myInt() {Value=left.Value + right};
  }

  public override string ToString()
  {
    return string.Format("C{0,3:D3}",Value); //OriginalGriff's code
  } 

  public bool FromString(string input)
  {
    System.Text.RegularExpressions.Match m = System.Text.RegularExpressions.Regex.Match(input, @"(?<string>[A-Za-z]+)(?<number>\d+)"); // Kim's code

    if (m.Success)
      this.Value = m.Groups["number"].Value;

    return m.Success;
  }
}

Good approach, and if I may add
class myInt{
public int Value;
public static myInt operator +(myInt left,int right)
{return new myInt(){Value=left.Value + right};}
public override string ToString() {return string.Format("C{0,3:D3}",Value);} //OriginalGriff's code
public bool FromString(string input){
System.Text.RegularExpressions.Match m = System.Text.RegularExpressions.Regex.Match(input, @"(?<string>[A-Za-z]+)(?<number>\d+)"); // Kim's code
if (m.Success) this.Value = m.Groups["number"].Value;
return m.Success;
}
}
etc :)

Solution 4

int c1 = 0xC001;
int c12 = 0x12;
int answer = c1 + c12;
Console.WriteLine("The answer is {0:X}", answer);

Solution 1

Well, if you take any type here. It will work according to their predefined logics and syntaxes.

Well, I would have suggested "dynamic" type

Ex:

dynamic b = "C001" + "12"

Will become C00112

So I think you should use string functions for this.

Such as Substring except first character you can go with remainingssss

001 + 12 = 013 with pading of zeros.

:)

Thanks :)

You can't, not directly.
You need to break the string "C001" into it's two parts: string and integer.
If this is a fixed format, it's easy:

string inText = "C001";
int inVal = 12;
string text = inText.Substring(0, 1);
string number = inText.Substring(1);
int val = int.Parse(number);
val += inVal;
string outText = string.Format("{0}{1,3:D3}", text, val);

If it isn't fixed, then it gets a little harder - but not much!
