You can use the following code for it:
您可以使用以下代码：
foreach (DataControlField col in gridReviews.Columns)
{
if (col.HeaderText == "Name")
{
col.Visible = false;
}
}

You can access the gridview by column name indirectly if you can access the data you used to bind the gridview and the gridview columns are in the same order as the datatable (and AutoGenerateColumns = false):
如果您可以访问用于绑定 gridview 的数据，并且 gridview 列与数据表的顺序相同（并且 AutoGenerateColumns = false），则您可以通过列名间接访问 gridview：
//Make ID column invisible by column name
gv.Columns[dt.Columns[ID].Ordinal].Visible = false;
