DataGridView的行数VS Rows.Count [英] DataGridView RowCount vs Rows.Count

问题描述

如果我有一个DataGridView uxChargeBackDataGridView 。

If I have a DataGridView uxChargeBackDataGridView.

有以下几种语法不同，但实际上是相同的：

Are the following syntactically different but effectively the same?:

int numRows = uxChargeBackDataGridView.Rows.Count;
int numRowCount = uxChargeBackDataGridView.RowCount;

如果 uxChargeBackDataGridView 为空，则两者相等为1;它因此在逻辑上站立，如果其中任一等于1，我可以假设用户没有输入任何数据？

If uxChargeBackDataGridView is empty then both are equal to 1; does it therefore logically stand that if either of these is equal to 1 I can assume the user has not input any data?

WinFroms有一个按钮运行 - 我可以用上面的测试，如果此按钮启用与否，即只启用按钮时的行号是>决定; 1 ？

The WinFroms has a button RUN - could I use the above test to decide if this button is enabled or not i.e only enable the button when the number of rows is >1 ?

推荐答案

这两个语句是相同的。但是，有一点要记住的是一个空的datagridview只有当 AllowUsersToAddRow 属性设置为true 1的纪录。否则，行数为0

Both statements are the same. However, one thing to remember is that an "empty" datagridview has 1 record only if the AllowUsersToAddRow property is set to true. Otherwise, the row count will be 0.

编辑：
我想补充，替代MMK的回答，如果你不改变行数，手动或编程，它们将返回相同的值。请参见 http://msdn.microsoft.com/en-us/library /system.windows.forms.datagridview.rowcount.aspx 。
