Summary
Gets or sets the requested resource from the server.

Syntax
C#
C++/CLI
Python
public string Target { get; set; } 
public: 
property String^ Target { 
   String^ get(); 
   void set (    String^ ); 
} 
Target # get and set (TargetFields) 

Property Value

A System.String used to specify the original named resource (often the name of a file on the server).

Remarks

This field is used to specify the original named resource (image name/path on the server). If this property is null or System.String.Empty then the image is determined by other means.

If the value of this field is not specified the server will use the path of the URI specified in an HTTP request
