用字符串数据列替换Byte []数据列 [英] Replace Byte[] Data Column With a String Data Column

问题描述

感谢您的关注:)

我正在尝试纠正以下情况:

我有一个DataGridView，它显示来自任意select语句的数据. select语句的数据在DataTable中返回，该数据表被指定为DataGridView的数据源.

当DataColumn返回Byte []类型的数据时，会发生此问题.我想出了如何删除此列，但我认为这不是一个很好的解决方案.

我宁愿在DataColumn中显示一条消息，例如< Binary Data>"给用户，而不是莫名其妙地删除一列数据.

是否可以用String类型的DataColumn替换Byte []类型的DataColumn?

Thanks for looking :)

I have the following situation I''m trying to remedy:

I have a DataGridView, which shows data from an arbitrary select statement. The select statement''s data is returned in a DataTable, which is assigned as the DataSource for the DataGridView.

The problem occurs when a DataColumn returns Byte[] type data. I figured out how to just delete this column, which I don''t consider to be a good solution.

I''d rather show a message in the DataColumn like "<Binary Data>" to the user instead of inexplicably deleting a column of data.

Is there a way of replacing the Byte[] type DataColumn with a String type DataColumn?
Is there a setting I don''t know about in a DataGridView which would do this (like the DefaultNull setting, but for a Byte[] type column)?
