なぜMrSystem.Windows.Forms.TextBoxです、テキスト：dsadasdはapearringを維持しますか？

Question

ケース2：

   if (jk.SelectedIndex == 0) 
       { 
        if (stat.SelectedIndex == 0) 
        { 
         result = "Mr" + name; 
        } 
        else 
        { 
         result = "Mr" + name; 
        } 
       } 
       else 
       { 
        if (stat.SelectedIndex == 0) 
        { 
         result = "Mrs" + name; 
        } 
        else 
        { 
         result = "Ms" + name; 
        } 
       } 
       txbx1.Text = result; 
       break; 

これは私がここで使用したコードですが、 たび、これは System.Windows.Forms.TextBox、テキスト現れ続けるボタンをクリックします：dsndaslkdnaを。 私はtxtを使わずにtxbx1で変更しようとしましたが、エラーになるのはどれですか？
