ServicePoint のハッシュ コードを取得します。
Overrides Public Function GetHashCode() As Integer
[C#]
public override int GetHashCode();
[C++]
public: int GetHashCode();
[JScript]
public override function GetHashCode() : int;
戻り値
ServicePoint のハッシュ コード。
解説
A.Equals(B) が true の場合、 ServicePoint A および B のハッシュ コードは同じです。
このメソッドは、 Object.GetHashCode メソッドを実装します。
使用例
[Visual Basic, C#, C++] GetHashCode メソッドを使用して、2 つの HttpWebRequest インスタンスが同じ ServicePoint を示しているかどうかを判断する例を次に示します。
' Create the first 'HttpWebRequest' object.
Dim myWebRequest1 As HttpWebRequest = CType(WebRequest.Create("https://www.microsoft.com"), HttpWebRequest)
' The response object of 'HttpWebRequest' is assigned to a 'HttpWebResponse' variable.
Dim myWebResponse1 As HttpWebResponse = CType(myWebRequest1.GetResponse(), HttpWebResponse)
Dim myServicePoint1 As ServicePoint = myWebRequest1.ServicePoint
' Create the second 'HttpWebRequest' object with the same hostfragment as above.
Dim myWebRequest2 As HttpWebRequest = CType(WebRequest.Create("https://www.microsoft.com/windows"), HttpWebRequest)
Dim myWebResponse2 As HttpWebResponse = CType(myWebRequest2.GetResponse(), HttpWebResponse)
Dim myServicePoint2 As ServicePoint = myWebRequest2.ServicePoint
Console.WriteLine("The 'HashCode' for the first connection is:" + myServicePoint1.GetHashCode().ToString())
Console.WriteLine("The 'HashCode' for the second connection is:" + myServicePoint2.GetHashCode().ToString())
' Check whether the first and second 'HttpWebRequest' objects connecting to the same internet
' server are using the same 'ServicePoint' or not
If myServicePoint1.GetHashCode().Equals(myServicePoint2.GetHashCode()) Then
Console.WriteLine(ControlChars.Cr + "Two connections are created to the same Internet Server")
Console.WriteLine("So same 'ServicePoint' is used for both the Connections")
End If
