ResXResourceReader.BasePath Property

public:
 property System::String ^ BasePath { System::String ^ get(); void set(System::String ^ value); };

public string BasePath { get; set; }

public string? BasePath { get; set; }

member this.BasePath : string with get, set

Public Property BasePath As String

Property Value

A path that, if prepended to the relative file path specified in a ResXFileRef object, yields an absolute path to a resource file.

Exceptions

Examples

The following example creates an XML resource file that contains images of dog breeds, and also creates a string resource that specifies the application that created the resource. ResXFileRef objects are used to store the path to the images rather than storing the binary images themselves in the resource file. The example sets the BasePath property so that the relative file paths in the images' file names are interpreted as subdirectories of a directory named C:\data\.

Note that you must add a reference to System.Drawing.dll to compile the project successfully. The example also requires that the necessary images exist in a directory named C:\data\images\.

Remarks

The BasePath property is used to resolve relative file path references that are assigned to the FileName property of ResXFileRef objects. By default, its value is String.Empty, and relative file path references are resolved in relationship to the current directory returned by the Environment.CurrentDirectory property. You should set this property before you begin enumerating resources.
