c# - Asp.net C#データベース挿入エラー

Question

asp.net で単純なアプリケーションを実行しています。このアプリケーションは、さまざまなページのテキストボックスから入力を受け取り、最後のページでアダプターを介して挿入メソッドを使用しています。テキストボックスに hjihi のようなダミー入力を使用すると、例外が発生しません。しかし、フィールドに適切な入力を使用すると、このページ全体が恐ろしいエラーになります。検索しましたが、適切な回答が得られませんでした。

例外の詳細: System.Data.SqlClient.SqlException: 文字列またはバイナリデータが切り捨てられます。

このエラーは、指定された列タイプよりも長い/大きいデータを挿入しようとしていることを示しています。簡単な例: varchar(200) 型の列を指定しましたが、長さ 500 の文字列を挿入しようとしています。

このような例外を防ぐために、入力されたデータの何らかのクライアント側 (もちろんサーバー側) の検証を実装することをお勧めします。
