Environment.TickCount 屬性

public:
 static property int TickCount { int get(); };

public static int TickCount { get; }

static member TickCount : int

Public Shared ReadOnly Property TickCount As Integer

屬性值

32 位元帶正負號的整數，包含自上一次電腦啟動後所經過的毫秒時間量。

範例

下列範例示範如何擷取 屬性所 TickCount 傳回值的正範圍。 屬性 TickCount 會在 之間 Int32.MinValue 迴圈，這是負數，每 Int32.MaxValue 49.8 天一次。 此程式碼範例會移除符號位，以產生非負數，其會每隔 24.9 天迴圈一次零到 MaxValue 一次。

// Sample for the Environment::TickCount property
// TickCount cycles between Int32::MinValue, which is a negative 
// number, and Int32::MaxValue once every 49.8 days. This sample
// removes the sign bit to yield a nonnegative number that cycles 
// between zero and Int32::MaxValue once every 24.9 days.
using namespace System;
int main()
{
   int result = Environment::TickCount & Int32::MaxValue;
   Console::WriteLine( "TickCount: {0}", result );
}

/*
This example produces an output similar to the following:

TickCount: 101931139
*/

// Sample for the Environment.TickCount property.

備註

此屬性的值衍生自系統計時器，並儲存為 32 位帶正負號的整數。 請注意，因為它衍生自系統計時器，所以 屬性的 TickCount 解析度僅限於系統計時器的解析度，這通常介於 10 到 16 毫秒的範圍內。

TickCount 不同于 DateTime.Ticks 屬性，這是自 1/0001/0001 12：00am 起經過的 100 奈秒間隔數目。

DateTime.Now使用 屬性可取得這部電腦上的目前本機日期和時間。
