我需要将小数或货币转换为整数

Question

I try to convert this number to int in C#, but I can't.

800,000.00 is the original number, I need 800000 .

I used that line, but it didn't work.

value = int.Parse(Txt_proyeccion.Text, NumberStyles.Any | NumberStyles.Number);

That original number is in a textbox in asp app.

thanks!

Try doing it in two steps:

1. Parse to decimal .

2. Cast to int (truncate or round).

For instance

// truncate: 80.97 -> 80
int value = (int) decimal.Parse(Txt_proyeccion.Text, NumberStyles.Any);

// round: 80.97 -> 81
int value = (int) Math.Round(decimal.Parse(Txt_proyeccion.Text, NumberStyles.Any));

Edit: You may want to specify format (eg CultureInfo.InvariantCulture ) in order to be sure that . is the decimal separator while , is the thousand separator:

using System.Globalization;

...

// truncate: 80.97 -> 80
int value = (int) decimal.Parse(
  Txt_proyeccion.Text, 
  NumberStyles.Any,
  CulureInfo.InvariantCulture);

// round: 80.97 -> 81
int value = (int) Math.Round(decimal.Parse(
  Txt_proyeccion.Text, 
  NumberStyles.Any,
  CulureInfo.InvariantCulture));

Why on earth people are converting to string and back to a number I have no idea.

float cash = 800000.49;
int number = (int)cash;

OR

int number = (int)Math.Floor(cash);

OR

int number = (int) Math.Round(cash);

You get the idea.
