Definisi

Ruang nama:

System

Rakitan:

System.Runtime.dll

Sumber:

Uri.cs

Mendapatkan bagian instans yang Uri ditentukan.

public:
 System::String ^ GetLeftPart(UriPartial part);

public string GetLeftPart (UriPartial part);

member this.GetLeftPart : UriPartial -> string

Public Function GetLeftPart (part As UriPartial) As String

Parameter

part

UriPartial

Salah satu nilai enumerasi yang menentukan akhir bagian URI untuk dikembalikan.

Mengembalikan

String

Bagian instans yang Uri ditentukan.

Pengecualian

InvalidOperationException

Instans saat ini Uri bukan instans absolut.

ArgumentException

Yang ditentukan part tidak valid.

Contoh

Contoh berikut membuat instans Uri dan menulis jalur ke konsol.

// Create Uri
Uri^ uriAddress = gcnew Uri( "http://www.contoso.com/index.htm#search" );
Console::WriteLine( uriAddress->Fragment );
Console::WriteLine( "Uri {0} the default port ", uriAddress->IsDefaultPort ? (String^)"uses" : "does not use" );

Console::WriteLine( "The path of this Uri is {0}", uriAddress->GetLeftPart( UriPartial::Path ) );
Console::WriteLine( "Hash code {0}", uriAddress->GetHashCode() );
// The example displays output similar to the following:
//        #search
//        Uri uses the default port
//        The path of this Uri is http://www.contoso.com/index.htm
//        Hash code -988419291

// Create Uri
Uri uriAddress = new Uri("http://www.contoso.com/index.htm#search");
Console.WriteLine(uriAddress.Fragment);
Console.WriteLine("Uri {0} the default port ", uriAddress.IsDefaultPort ? "uses" : "does not use");

Console.WriteLine("The path of this Uri is {0}", uriAddress.GetLeftPart(UriPartial.Path));
Console.WriteLine("Hash code {0}", uriAddress.GetHashCode());
// The example displays output similar to the following:
//        #search
//        Uri uses the default port
//        The path of this Uri is http://www.contoso.com/index.htm
//        Hash code -988419291

// Create Uri
let uriAddress = Uri "http://www.contoso.com/index.htm#search"
printfn $"{uriAddress.Fragment}"
printfn $"""Uri {if uriAddress.IsDefaultPort then "uses" else "does not use"} the default port """

printfn $"The path of this Uri is {uriAddress.GetLeftPart UriPartial.Path}"
printfn $"Hash code {uriAddress.GetHashCode()}"
// The example displays output similar to the following:
//        #search
//        Uri uses the default port
//        The path of this Uri is http://www.contoso.com/index.htm
//        Hash code -988419291

' Create Uri
Dim uriAddress As New Uri("http://www.contoso.com/index.htm#search")
Console.WriteLine(uriAddress.Fragment)
Console.WriteLine("Uri {0} the default port ", If(uriAddress.IsDefaultPort, "uses", "does not use")) 

Console.WriteLine("The path of this Uri is {0}", uriAddress.GetLeftPart(UriPartial.Path))
Console.WriteLine("Hash code {0}", uriAddress.GetHashCode())
' The example displays output similar to the following:
'        #search
'        Uri uses the default port
'        The path of this Uri is http://www.contoso.com/index.htm
'        Hash code -988419291

Keterangan

Metode mengembalikan GetLeftPart string yang berisi bagian paling kiri dari string URI, diakhiri dengan bagian yang ditentukan oleh part.

GetLeftPart termasuk pemisah dalam kasus berikut:

• Scheme termasuk pemisah skema.
• Authority tidak menyertakan pemisah jalur.
• Path termasuk pemisah jalur dan pemisah apa pun dalam URI asli hingga pemisah kueri atau fragmen.
• Query Pathtermasuk , ditambah kueri dan pemisahnya.

Contoh berikut menunjukkan URI dan hasil panggilan GetLeftPart dengan , , AuthorityPath, atau QueryScheme.
