Question

我有一个程序会在某些条件下动态添加行，我尝试以这种方式实现该功能：

if (student.UUID == AppliedStudent)
{
    using (DataGridViewRow row = new DataGridViewRow())
    {
        row.SetValues(new object[] { lesson.Name, Course.Course_Name, lesson.Level, lesson.Time, Teacher.C_Name, lesson.Price, Classroom.Classroom_Name });
        row.DefaultCellStyle.BackColor = Color.LightGreen;
        row.DefaultCellStyle.SelectionBackColor = Color.SkyBlue;
        dataGridView1.Rows.Add(row);
    }
}

使用此代码，它确实可以添加行，但它们都是空的，所有这些行都没有数据。（已确认lesson，course和Teacher不是null。）任何人都可以提供帮助吗？谢谢！

我终于自己弄明白了，我将row.SetValues替换为row.CreateCells：

if (student.UUID == AppliedStudent)
{
    DataGridViewRow row = new DataGridViewRow();
    row.CreateCells(dataGridView1, lesson.Name, Course.Course_Name, lesson.Level, lesson.Time, Teacher.C_Name, lesson.Price, Classroom.Classroom_Name);
    row.DefaultCellStyle.BackColor = Color.LightGreen;
    row.DefaultCellStyle.SelectionBackColor = Color.SkyBlue;
    dataGridView1.Rows.Add(row);
}

使用此代码可以很好地工作。谢谢大家的帮助！

您需要省略using部分。之后将处理row对象：

if (student.UUID == AppliedStudent)
{
    DataGridViewRow row = new DataGridViewRow();
    row.SetValues(new object[] { lesson.Name, Course.Course_Name, lesson.Level, lesson.Time, Teacher.C_Name, lesson.Price, Classroom.Classroom_Name });
    row.DefaultCellStyle.BackColor = Color.LightGreen;
    row.DefaultCellStyle.SelectionBackColor = Color.SkyBlue;
    dataGridView1.Rows.Add(row);
}
