CLS 準拠の代替
System.Decimal.ToInt64(Decimal)

``````public:
static System::UInt32 ToUInt32(System::Decimal d);``````
``````[System.CLSCompliant(false)]
public static uint ToUInt32 (decimal d);``````
``````[<System.CLSCompliant(false)>]
static member ToUInt32 : decimal -> uint32``````
``Public Shared Function ToUInt32 (d As Decimal) As UInteger``

d
Decimal

#### 戻り値

UInt32

`d` の値と等価な 32 ビット符号なし整数。A 32-bit unsigned integer equivalent to the value of `d`.

#### 例外

`d` が負か MaxValue を超えています。`d` is negative or greater than MaxValue.

## 例

``````using System;

## 注釈

Decimal代入演算子を使用して、値を32ビット符号なし整数に変換することもでき Explicit ます。You can also convert a Decimal value to an 32-bit unsigned integer by using the Explicit assignment operator. 演算子は縮小変換を実行するため、キャスト演算子を C# で使用するか、Visual Basic の変換関数を使用する必要があります。Because the operator performs a narrowing conversion, you must use a casting operator in C# or a conversion function in Visual Basic.
