Mendapatkan atau mengatur jalur dasar untuk jalur file relatif yang ditentukan dalam ResXFileRef objek.

Jalur yang, jika ditambahkan ke jalur file relatif yang ditentukan dalam ResXFileRef objek, menghasilkan jalur absolut ke file sumber daya.
Pengecualian
Dalam operasi set, nilai tidak dapat ditentukan karena file sumber daya XML telah diakses dan sedang digunakan.
Contoh
Contoh berikut membuat file sumber daya XML yang berisi gambar ras anjing, dan juga membuat sumber daya string yang menentukan aplikasi yang membuat sumber daya. ResXFileRef objek digunakan untuk menyimpan jalur ke gambar daripada menyimpan gambar biner itu sendiri dalam file sumber daya. Contoh mengatur BasePath properti sehingga jalur file relatif dalam nama file gambar ditafsirkan sebagai subdirektori direktori bernama C:\data\.

Perhatikan bahwa Anda harus menambahkan referensi ke System.Drawing.dll agar proyek berhasil dikompilasi. Contoh ini juga mengharuskan gambar yang diperlukan ada di direktori bernama C:\data\images\.
Keterangan
Properti BasePath digunakan untuk mengatasi referensi jalur file relatif yang ditetapkan ke FileName properti ResXFileRef objek. Secara default, nilainya adalah String.Empty, dan referensi jalur file relatif diselesaikan dalam hubungan dengan direktori saat ini yang dikembalikan oleh Environment.CurrentDirectory properti . Anda harus mengatur properti ini sebelum mulai menghitung sumber daya.
