The straightforward method:
直截了当的方法：
if (dgv.Columns.Contains("Address") && dgv.Columns["Address"].Visible)
{
// do stuff
}

You can test the column visibility using the Visibleproperty:
您可以使用以下Visible属性测试列可见性：
if (column.Visible)
{
// Do Stuff
}
This will tell you if the column should be displayed.
这将告诉您是否应显示该列。
You can get the column via this call if you know the index:
如果您知道索引，则可以通过此调用获取列：
DataColumn column = dGV.Columns[index];
If the column is displayed but off the screen I don't know how you'd test for that.
如果该列显示但不在屏幕上，我不知道您将如何进行测试。

Loop through the columns, checking the heading (I assume that's what you're looking for) and the Visible property.
遍历列，检查标题（我假设这就是您要查找的内容）和 Visible 属性。

Firstly verify if the column exists and then you verify its visibility.
首先验证该列是否存在，然后验证其可见性。
Calling the column's property for a column that does not exist will crash.
为不存在的列调用列的属性将崩溃。
if (dgv.Columns.Contains("Address")
{
if ( dgv.Columns["Address"].Visible )
{
}
}

var dataGridViewColumn = dgv.Columns["Address"];
if (dataGridViewColumn != null && dataGridViewColumn.Visible)
{
//do stuff
}
