String num = "93456"
decimal decinum = Convert.ToDecimal(num);
var newnum = decinum.ToString();
I need to convert string value into decimal value and back to string value
For instance, 93456 string format in to 93.456 decimal format then back to 93.456 string format.
I need to place a decimal after two fist digits of a string.
Here's my attempt:
String myString = "93456";
if (myString.Length > 2)
{
myString = myString.Insert(2, Thread.CurrentThread.CurrentCulture.NumberFormat.NumberDecimalSeparator);
}
var myDecimal = decimal.Parse(myString);
Console.WriteLine(myDecimal);
Console.WriteLine(myDecimal.ToString());
You can try this
string num = TextBox1.Text; //"93456.12";
if (num.Length > 2)
{
decimal decNumber = Convert.ToDecimal(num.Substring(0, 2) + "." + num.Substring(2, num.Length - 2).Replace(".",""));
string strNumber = Convert.ToString(decNumber);
}
This may help you:
string num1 = "93456";
int value = Convert.ToInt32(num1);
int digits = (num1.Length - 2) > 0 ? (num1.Length - 2) : 0;
decimal number1 = value / Convert.ToDecimal(Math.Pow(10, digits));
string result = number1.ToString();
Yet another way:
string num = "93456";
decimal decinum = decimal.Parse(num);
string newnum = decinum.ToString("#,#", new NumberFormatInfo { NumberGroupSeparator = "." });
string num = "9312";
string newNum = num.Length > 2 ? num.Insert(2, ".") : num + ".000";
decimal newDecimal;
if (Decimal.TryParse(newNum, out newDecimal))
Console.WriteLine(newDecimal);
else
Console.WriteLine("not a valid decimal '{0}'.", newDecimal);
decimal num = 93456;
StringBuilder sb = new StringBuilder(num.ToString());
if (sb.Length > 2)
sb.Insert(2, Thread.CurrentThread.CurrentCulture
.NumberFormat.CurrencyDecimalSeparator);
Console.WriteLine(sb);
num = decimal.Parse(sb.ToString());
Console.WriteLine(num);
Update we don't have alot of string manipulation,so don't need using StringBuilder. also according the question we should use NumberDecimalSeparator instead of CurrencyDecimalSeparator
decimal num = 93456;
string str = num.ToString();
if (str .Length > 2)
str .Insert(2, Thread.CurrentThread.CurrentCulture
.NumberFormat.NumberDecimalSeparator);
Console.WriteLine(str);
num = decimal.Parse(str);
Console.WriteLine(num);
CurrencyDecimalSeparator and not NumberDecimalSeparator?
