提问by Umar
Im using this code for formatting my textbox.
我使用此代码格式化我的文本框。
Public Function TextFormat(ByVal sString As String) As String
Dim num1 As Decimal
Try
num1 = Convert.ToDecimal(sString)
TextFormat = FormatNumber(num1, 2)
Return TextFormat
Catch
TextFormat = sString
End Try
End Function
-the problem is its rounding off the number i input .. sample
- 问题是它四舍五入我输入的数字..样本
textbox.text = "5999.99" it displaying "6000.00" how can i disable the auto rounding off number . or is there any other code for formatting text? "###,###,###.##" << it should be like this
textbox.text = "5999.99" 它显示 "6000.00" 如何禁用自动四舍五入数字。或者是否有其他用于格式化文本的代码？"###,###,###.##" << 应该是这样的

use ToString Instead FormatNumber.
使用 ToString 而不是 FormatNumber。
Public Function TextFormat(ByVal sString As String) As String
Dim num1 As Decimal
If Double.TryParse(sString, num1) Then
Return num1.ToString("G") ' or ToString("F2") or ToString("0.00")
Else
Return sString
End If
End Function

Try to use:
尝试使用：
Dim number = Math.Truncate(CInt(textbox.text) * 1000) / 1000;
textbox.text = number.toString
