Question

我的文本框有问题。问题是我初始化了属性

textBox1.RightToLeft = RightToLeft.Yes;

当我输入阿拉伯字符时，它输入正确，但如果输入以下内容则会出现问题字符串

66 /جح/

96

/之后的数字96，但是编辑器不允许这样写，所以当我读它时它改变了它的字符：

جح/ 66/96

public class DbHelper extends SQLiteOpenHelper {
    private static final int DATABASE_VERSION = 1;
    private static final String DATABASE_NAME = "triviaQuiz";
    private static final String TABLE_QUEST = "quest";
    private static final String KEY_ID = "id";
    private static final String KEY_QUES = "question";
    private static final String KEY_ANSWER = "answer"; //correct option
    private static final String KEY_OPTA= "opta"; //option a
    private static final String KEY_OPTB= "optb"; //option b
    private static final String KEY_OPTC= "optc"; //option c
    private SQLiteDatabase dbase;
    public DbHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }
    @Override
    public void onCreate(SQLiteDatabase db) {
        dbase=db;
        String sql = "CREATE TABLE IF NOT EXISTS " + TABLE_QUEST + " ( "
                + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + KEY_QUES
                + " TEXT, " + KEY_ANSWER+ " TEXT, "+KEY_OPTA +" TEXT, "
                +KEY_OPTB +" TEXT, "+KEY_OPTC+" TEXT)";
        db.execSQL(sql);
        addQuestions();
        //db.close();
    }
    private void addQuestions()
    {
        Question q1 = new Question("Q1?", "Ans A", "" +
                "Ans B", "Ans C", "Ans A");
        this.addQuestion(q1);

        Question q2 = new Question("Q2?", "Ans A", "" +
                "Ans B", "Ans C", "Ans C");
        this.addQuestion(q2);

        Question q3 = new Question("Q3?", "Ans A", "" +
                "Ans B", "Ans C", "Ans B");
        this.addQuestion(q3);

        Question q4 = new Question("What does q4 do?", "Ans A", "" +
                "Ans B", "Ans C", "Ans C");
        this.addQuestion(q4);

        Question q5 = new Question("What does q5 do?", "Ans A", "" +
                "Ans B", "Ans C", "Ans B");
        this.addQuestion(q5);


    }

    // Adding new question
    public void addQuestion(Question quest) {
        //SQLiteDatabase db = this.getWritableDatabase();
        ContentValues values = new ContentValues();
        values.put(KEY_QUES, quest.getQUESTION());
        values.put(KEY_ANSWER, quest.getANSWER());
        values.put(KEY_OPTA, quest.getAnsA());
        values.put(KEY_OPTB, quest.getAnsB());
        values.put(KEY_OPTC, quest.getAnsC());
        // Inserting Row
        dbase.insert(TABLE_QUEST, null, values);
    }
    public List<Question> getAllQuestions() {
        List<Question> quesList = new ArrayList<Question>();
        // Select All Query
        String selectQuery = "SELECT  * FROM " + TABLE_QUEST;
        dbase=this.getReadableDatabase();
        Cursor cursor = dbase.rawQuery(selectQuery, null);
        // looping through all rows and adding to list
        if (cursor.moveToFirst()) {
            do {
                Question quest = new Question();
                quest.setID(cursor.getInt(0));
                quest.setQUESTION(cursor.getString(1));
                quest.setANSWER(cursor.getString(2));
                quest.setAnsA(cursor.getString(3));
                quest.setAnsB(cursor.getString(4));
                quest.setAnsC(cursor.getString(5));
                quesList.add(quest);
            } while (cursor.moveToNext());
        }
        // return quest list
        return quesList;
    }
    public int rowcount()
    {
        int row=0;
        String selectQuery = "SELECT  * FROM " + TABLE_QUEST;
        SQLiteDatabase db = this.getWritableDatabase();
        Cursor cursor = db.rawQuery(selectQuery, null);
        row=cursor.getCount();
        return row;
    }
}

结果：

 var LRM = ((char)0x200E).ToString();
 lbldate.Text = ddlTrnNoYears.SelectedItem.Text+'/' + LRM + ddlTrainingMonth.SelectedItem.Text + LRM +'/'+ddlTrainingDay.SelectedItem.Text;

用阿拉伯语言的文本框
