根據(jù)moduleName反射到某個類某個方法

      [WebMethod(Description = "得到報表數(shù)據(jù)")]
      [SoapHeader("Credentials")]
      public DataSet GetRptData(string moduleName, DataSet dsCondition, string userNo)
      {
          DataSet ds = new DataSet();
          Type type = Type.GetType("Regentsoft.Plugin.Report.Bll." + moduleName + ",Regentsoft.Plugin.Report.Bll");
          if (type == null)
              return ds;

          object dObj = Activator.CreateInstance(type);
          //屬性
          System.Reflection.PropertyInfo property = type.GetProperty("UserNo");
          property.SetValue(dObj, userNo, null);
          System.Reflection.PropertyInfo property1 = type.GetProperty("DsCondition");
          property1.SetValue(dObj, dsCondition, null);

          //獲取方法的信息
          System.Reflection.MethodInfo method = type.GetMethod("Calculate");
          //調(diào)用方法的一些標(biāo)志位，這里的含義是Public并且是實例方法，這也是默認(rèn)的值
          System.Reflection.BindingFlags flag = System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance;
          //調(diào)用方法，用一個object接收返回值
          object obj = method.Invoke(dObj, flag, null, null, null);

          if (obj != null)
          {
              ds = (DataSet)obj;
          }

          return ds;
      }

轉(zhuǎn)換成DataView操作Datatable

       /// <summary>
        /// 取得選中的記錄
        /// </summary>
        /// <param name="dt"></param>
        /// <param name="selectFieldName">選擇字段名</param>
        /// <returns></returns>
        public static DataTable GetDataTableSelectData(DataTable dt, string selectFieldName)
        {
            if (dt == null)
                return null;

            DataView dv = new DataView(dt);
            dv.RowFilter = string.Format("{0} = 1", selectFieldName);

            return dv.ToTable();
        }
