Contoh

Contoh kode berikut menunjukkan cara menggunakan metode IsAbsolute, IsAppRelative, dan ToAppRelative.

StringBuilder sb2 = new StringBuilder();
String pathstring1 = Context.Request.CurrentExecutionFilePath.ToString();
sb2.Append("Current Executing File Path = " + pathstring1.ToString() + "<br />");
sb2.Append("Is Absolute = " + VirtualPathUtility.IsAbsolute(pathstring1).ToString() + "<br />");
sb2.Append("Is AppRelative = " + VirtualPathUtility.IsAppRelative(pathstring1).ToString() + "<br />");
sb2.Append("Make AppRelative = " + VirtualPathUtility.ToAppRelative(pathstring1).ToString() + "<br />");
Response.Write(sb2.ToString());

Dim sb2 As New StringBuilder()
Dim pathstring1 As String = Context.Request.CurrentExecutionFilePath.ToString()
sb2.Append("Current Executing File Path = " & pathstring1.ToString() & "<br />")
sb2.Append("Is Absolute = " & VirtualPathUtility.IsAbsolute(pathstring1).ToString() & "<br />")
sb2.Append("Is AppRelative = " & VirtualPathUtility.IsAppRelative(pathstring1).ToString() & "<br />")
sb2.Append("Make AppRelative = " & VirtualPathUtility.ToAppRelative(pathstring1).ToString() & "<br />")
Response.Write(sb2.ToString())

Keterangan

Jalur virtual hanya dapat berupa operator root (tilde [~]), atau dapat dimulai dengan operator root. Jika virtualPathnull, pengecualian ArgumentNullException akan dinaikkan. Jika virtualPath adalah string kosong (""), metode IsAppRelative mengembalikan false.

Nota

"~ filename " bukan jalur virtual yang valid dan mengembalikan false untuk metode IsAppRelative.
