I've a predefined string format. For instance '>>>,>>>,>>9.99' this means that the system should display string in this '500,000,000.10'. The format can change based on the users using it. How can I write a common function to display stings on the given format passing the input value and the format as the parameter using C#
您可以将ToString
方法与标准或自定义格式字符串一起使用
For example:
string format = "{0:000,000,000.00}"; string val = 12.3456; Console.WriteLine(string.Format(format, value)); // it prints "000,000,123.23"
You can read more about formating values here http://www.csharp-examples.net/string-format-double/
decimal value = 1.2345;
string rounded = value.ToString("d2");
private string sDecimalFormat = "0.00";
decimal d = 120M;
txtText.Text = d.ToString(sDecimalFormat);
You could then have a setting for decimal format eg:
txtText.Text = d.ToString(Settings.DecimalFormat);
String.formate can be used for formating.
Go there if you want examples http://www.csharp-examples.net/string-format-double/
I think the following might work:
String result = String.Format(fmt.Replace('>', '#').Replace('9', '0'), inpString);
fmt
being the format you want to use and inpString
being the string entered by the user.
Just replace the >
with #
and the 9
with 0
and it'll be a valid .Net formatstring.
There is a Format
method on String
.
String.Format("{0:X}", 10); // prints A (hex 10)
I dont seem to understand how you can make 500,000,000.10 from >>>,>>>,>>9.99' but I believe the answer would be
But I assume something you are looking for is: string.Format("500,000,00{0:0.##}", 9.9915)
You can then make a method like
Public string GetString(string Format, object value)
{
return string.Format(Format, value);
}
Something like this?
