c#中DataTable转List的2种方法示例

public List<Dictionary<string, object>> DatatoTable(DataTable dt)
{
 
    List<Dictionary<string, object>> list = new List<Dictionary<string, object>>();
    foreach (DataRow dr in dt.Rows)//每一行信息，新建一个Dictionary<string,object>,将该行的每列信息加入到字典
    {
        Dictionary<string, object> result = new Dictionary<string, object>();
        foreach (DataColumn dc in dt.Columns)
        {
            result.Add(dc.ColumnName, dr[dc].ToString());
        }
        list.Add(result);
    }
    return list;
}

public class TabletoList
    {
        public static List<T> TableToListModel<T>(DataTable dt) where T : new()
        {
            // 定义集合    
            List<T> ts = new List<T>();
 
            // 获得此模型的类型   
            Type type = typeof(T);
            string tempName = "";
 
            foreach (DataRow dr in dt.Rows)
            {
                T t = new T();
                // 获得此模型的公共属性      
                PropertyInfo[] propertys = t.GetType().GetProperties();
                foreach (PropertyInfo pi in propertys)
                {
                    tempName = pi.Name;  // 检查DataTable是否包含此列    
 
                    if (dt.Columns.Contains(tempName))
                    {
                        // 判断此属性是否有Setter      
                        if (!pi.CanWrite) continue;
 
                        object value = dr[tempName];
                        if (value != DBNull.Value)
                            pi.SetValue(t, value, null);
                    }
                }
                ts.Add(t);
            }
            return ts;
        }
    }
