C# : Check value stored inside string object is decimal or not

Question

in C# , how can i check whether the value stored inside a string object( Ex : string strOrderId=\"435242A\") is decimal or not?

Answer 1

In case if we do not want use extra variable.

string strOrderId = "435242A";

bool isDecimal = isDecimal(strOrderId);


public bool isDecimal(string value) {

  try {
    Decimal.Parse(value);
    return true;
  } catch {
    return false;
  }
}
