Visual Basic, How do I read each row in a datagrid?
提问by Patrick McDonald
I have a datagrid called DataGridView1, column A contains a name, column B contains a path to a file. How do I run some code for each row? What is the correct terminology for traversing a datagrid in this way?
我有一个名为 DataGridView1 的数据网格，A 列包含一个名称，B 列包含一个文件路径。如何为每一行运行一些代码？以这种方式遍历数据网格的正确术语是什么？
Example of what I need:
我需要的示例：
For each row in DataGridView1
MessageBox.Show DataGridView1.ColumnA.text & "," & DataGridView1.ColumnB.text
Thanks
谢谢

You were nearly there, you need something like the following:
你快到了，你需要像下面这样的东西：
For Each row As DataGridViewRow In DataGridView1.Rows
If Not row.IsNewRow Then
MessageBox.Show(row.Cells(0).Value.ToString & "," & row.Cells(1).Value.ToString)
End If
Next
EDIT:
编辑：
You need to check if the row.IsNewRow is not True if your DataGridView allows adding rows.
如果您的 DataGridView 允许添加行，您需要检查 row.IsNewRow 是否不为 True。
