Decimal Constructor (UInt32)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Initializes a new instance of Decimal to the value of the specified 32-bit unsigned integer.

This API is not CLS-compliant. 

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

Syntax

'Declaration
<CLSCompliantAttribute(False)> _
Public Sub New ( _
    value As UInteger _
)

[CLSCompliantAttribute(false)]
public Decimal(
    uint value
)

Parameters

Examples

The following code example creates several Decimal numbers using the constructor overload that initializes a Decimal structure with a UInt32 value.

' Example of the Decimal( UInt32 ) constructor.

Module Example

   ' Create a Decimal object and display its value.
   Sub CreateDecimal(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal value As UInt32, ByVal valToStr As String)

      Dim decimalNum As New Decimal(value)

      ' Format the constructor for display.
      Dim ctor As String = _
          String.Format("Decimal( {0} )", valToStr)

      ' Display the constructor and its value.
      outputBlock.Text &= String.Format("{0,-33}{1,16}", ctor, decimalNum) & vbCrLf
   End Sub

   Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)

      outputBlock.Text &= _
          "This example of the Decimal( UInt32 ) constructor " & _
          vbCrLf & "generates the following output." & vbCrLf & vbCrLf
      outputBlock.Text &= String.Format("{0,-33}{1,16}", "Constructor", "Value") & vbCrLf
      outputBlock.Text &= String.Format("{0,-33}{1,16}", "-----------", "-----") & vbCrLf

      ' Construct Decimal objects from UInt32 values.
      ' UInt32.MinValue and UInt32.MaxValue are not defined in VB.
      CreateDecimal(outputBlock, Convert.ToUInt32(0), """UInt32.MinValue""")
      CreateDecimal(outputBlock, Convert.ToUInt32(4294967295), _
          """UInt32.MaxValue""")
      CreateDecimal(outputBlock, Convert.ToUInt32(Integer.MaxValue), _
          "Integer.MaxValue")
      CreateDecimal(outputBlock, Convert.ToUInt32(999999999), "999999999")
      CreateDecimal(outputBlock, Convert.ToUInt32(&H40000000), "&H40000000")
      CreateDecimal(outputBlock, Convert.ToUInt32(&HC0000000L), "&HC0000000")
   End Sub
