遍历datatable

可以使用foreach循环或者for循环进行遍历DataTable。使用foreach循环遍历DataTable时，每次循环都会将DataTable中的一行数据转换为DataRow对象，方便获取行数据中的具体字段值。示例代码如下：

// 使用foreach循环遍历DataTable
foreach (DataRow row in dt.Rows)
{
    Console.WriteLine("ID: {0}, Name: {1}, Age: {2}", row["ID"], row["Name"], row["Age"]);
}

使用for循环遍历DataTable时，需要使用DataRowCollection集合的索引获取每一行数据。示例代码如下：

// 使用for循环遍历DataTable
for (int i = 0; i < dt.Rows.Count; i++)
{
    Console.WriteLine("ID: {0}, Name: {1}, Age: {2}", dt.Rows[i]["ID"], dt.Rows[i]["Name"], dt.Rows[i]["Age"]);
}
