C245の条件式が 'System :: Windows :: Forms :: DialogResult'型が不正です。

Question

フォルダを開いて結果をテキストボックスに入れようとしています。 しかし、ユーザーがフォルダを選択し、[OK]を押した場合、私がチェックしたときに、それは私にエラーを与える

C245 conditional expression of type 'System::Windows::Forms::DialogResult' is illegal 

これは、エラーは、私はちょうどDialogResultでそれをも試してみました

private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) { 
    System::Windows::Forms::DialogResult result = folderBrowserDialog1->ShowDialog(); 

    if (result = System::Windows::Forms::DialogResult::OK) 
    { 
     textBox1->Text = folderBrowserDialog1->SelectedPath; 
    } 
} 
}; 

ある部分であります:: OKですが、OKが宣言されていないというエラーメッセージが表示され、Googleを検索するとSystem :: Windows :: Forms :: DialogResult :: OKを代わりに使用する必要があります。

そして、これが

==を間違って何かをやっイム包みファイル全体のための私のソースコードは、しかし、あなたは、値の割り当てである=を使用している比較のためです。

これは動作するはずです：これは完全に働いた！

if (result == System::Windows::Forms::DialogResult::OK) 
{ 
    textBox1->Text = folderBrowserDialog1->SelectedPath; 
}
