ResXResourceReader.BasePath Propriedade

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

Valor da propriedade

Um caminho que, se preceder o caminho relativo do arquivo especificado em um objeto ResXFileRef, resulta em um caminho absoluto para um arquivo de recurso.

Exceções

Exemplos

O exemplo a seguir cria um arquivo de recurso XML que contém imagens de raças de cachorro e também cria um recurso de cadeia de caracteres que especifica o aplicativo que criou o recurso. ResXFileRef Os objetos são usados para armazenar o caminho para as imagens em vez de armazenar as próprias imagens binárias no arquivo de recurso. O exemplo define a BasePath propriedade para que os caminhos de arquivo relativos nos nomes de arquivo das imagens sejam interpretados como subdiretórios de um diretório chamado C:\data\.

Comentários

A BasePath propriedade é usada para resolve referências de caminho de arquivo relativo atribuídas à FileName propriedade de ResXFileRef objetos . Por padrão, seu valor é String.Emptye as referências de caminho de arquivo relativo são resolvidas em relação ao diretório atual retornado pela Environment.CurrentDirectory propriedade . Você deve definir essa propriedade antes de começar a enumerar recursos.
