C#获取DataGridView所有的列表名的详细方法

List<string> columnNames = dgvHdhcms.Columns
                           .Cast<DataGridViewColumn>()
                           .Select(col => col.Name)  // 或 col.HeaderText 获取显示标题
                           .ToList();

string name = column.Name;

string header = column.HeaderText;
column.HeaderText = "新标题";

string typeName = column.GetType().Name;

private void LoadColumnNames(DataGridView dgv)
{
    if (dgv?.Columns == null) return;
    // 获取所有列名
    var names = dgv.Columns.Cast<DataGridViewColumn>()
                      .Select(c => c.Name)
                      .ToList();
    // 输出示例
    foreach (var name in names)
    {
        Console.WriteLine($"列名: {name}");
    }

    // 可选：绑定到其他控件（如ComboBox）
    comboBox1.DataSource = names;
}

// 添加新列
dgvHdhcms.Columns.Add("newColumn", "动态列");
// 删除列后重新获取
dgvHdhcms.Columns.Remove("oldColumn");
var updatedNames = dgvHdhcms.Columns.Cast<DataGridViewColumn>().Select(c => c.Name);

// 仅获取按钮列
var buttonColumns = dgvHdhcms.Columns
    .Cast<DataGridViewColumn>()
    .Where(c => c is DataGridViewButtonColumn)
    .Select(c => c.Name);

// 获取数据源字段名（需检查是否已绑定）
if (dgvHdhcms.DataSource is DataTable dt)
{
    var sourceColumnNames = dt.Columns.Cast<DataColumn>().Select(dc => dc.ColumnName);
