注意table 列的参数类型，若不为string 需要详细声明 如 typeof(Int32)
public static IList<T> ConvertTo<T>(DataTable dt) where T : new()
{
IList<T> list = new List<T>();
if (dt == null || dt.Rows.Count <= 0)
{
return null;
}
Type type = typeof(T);
PropertyInfo[] propertys = type.GetProperties();//获取T的所有属性
try
{
foreach (DataRow dr in dt.Rows)
{
T t = new T();
foreach (PropertyInfo pi in propertys)
{
if (dt.Columns.Contains(pi.Name))
{
if (!pi.CanWrite) continue;
object value = dr[pi.Name];
if (value != DBNull.Value)
pi.SetValue(t, value, null);
}
}
list.Add(t);
}
}
catch (Exception ex)
{
list = null;
}
return list;
}
