Uri.Host Property

Silverlight

Other Versions

Gets the host component of this instance.

Namespace: System
Assembly: System (in System.dll)

Syntax

Copy

public string Host { get; }

Property Value

Type: System.String
A String that contains the host name. This is usually the DNS host name or IP address of the server.

Exceptions

Exception	Condition
InvalidOperationException	This property is valid only for an absolute Uri instance.

Remarks

The Host property gets the host component of this Uri instance. This property value does not include the port number.

Silverlight-based applications are cross-platform, so they run in most modern Web browsers, including Apple Safari version 2.0 and later on Apple Mac OS X. However, full parsing for UNC style paths in a Uri is supported only on Windows. Any backslashes in a Uri for the UriSchemeFile representing a UNC path are converted to forward slashes on Apple Mac OS X.

An example that displays this issue is below:

Uri testUri = Uri(@"file://\\computer\download\file.ext");

On Windows, this UNC path is converted to the following Uri:

file://computer/download/file.ext

The AbsolutePath is /download/file.ext.

The Host property is equal to: computer.

The IsUnc property is true.

The LocalPath property is \\computer\download\file.ext.

On Apple Mac OS X, this UNC path is converted to the following Uri:

file::////computer/download/file.ext

The AbsolutePath property is //computer/download/file.ext.

The Host property is an empty string.

The IsUnc property is false.

The LocalPath property is computer/download/file.ext.

Examples

The following example writes the host name (www.contoso.com) of the server to the console.

Copy


   Uri baseUri = new Uri("http://www.contoso.com:8080/");
   Uri myUri = new Uri(baseUri, "shownew.htm?date=today");

   outputBlock.Text += "Uri.Host: ";
   outputBlock.Text += myUri.Host;
   outputBlock.Text += "\n";
