地籍数据属性质检功能设计与实现

要质检的数据包括使用权宗地、所有权宗地、自然幢，属性质检规则如下：

使用权宗地、所有权宗地属性质检项如下：

1. 必填项

区县代码（QXDM）、宗地特征码（ZDTZM）、坐落（ZL）、定着物特征码（DZWTZM）、权力人（QLR）、面积单位（MJDW）。

2. 字段限制

1) 要素代码（YSDM）为空，或不为空必须是10位数字组成；

2) 宗地代码（ZDDM）为空，或不为空必须是19位、数字或字母组成；

3) 不动产单元号（BDCDYH）为空，或不为空必须是28位、数字或字母组成；

4) 宗地特征码（ZDTZM），2个字母组成，如果第一个字母是G、第二个字母只能是BDEFSXY中的一个，第一个字母是J、第二字母是ABCDEFSXY中一个，第一个字母是Z、第二个字母只能是W，无其他组合；

5) 定着物特征码（DZWTZM），宗地只能是W。

自然幢属性质检项如下：

1. 字段限制

1) 区县代码（QXDM）为空，或不为空只能是6位数字；

2) 要素代码（YSDM）为空，或不为空必须是10位数字组成；

3) 宗地代码（ZDDM）为空，或不为空必须是19位、数字或字母组成；

4) 不动产单元号（BDCDYH）为空，或不为空必须是28位、数字或字母组成；

5) 自然幢号（ZRZH）为空，或不为空必须是24位、数字或字母组成；

宗地宗海特征码（ZDZHTZM）为空，或不为空由2个字母组成，如果第一个字母是G、第二个字母只能是BDEFSXY中的一个，第一个字母是J、第二字母是ABCDEFSXY中一个，第一个字母是Z、第二个字母只能是W，无其他组合。

设计时，考虑通用性和可复用性，设计了质检类CheckFieldValue，并在此基础上设计了一宗地数据的宗地特征码、自然幢数据的宗地宗海特征码检查类ParcelCheckFieldValue。

如下：

}

其中，接口传入参数与质检结果相关返回参数设计如下：

using GeoJSON.Net.Feature;
using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;namespace GISWebService.HttpRequestContent
{/// <summary>/// 属性质检的传入参数/// </summary>public class CheckFieldsRequestBody{/// <summary>/// 图层/// </summary>[JsonProperty("layer")]public string Layer { get; set; }/// <summary>/// 要素集合/// </summary>[JsonProperty("feature")]public List<Feature> Feature { get; set; }}/// <summary>/// 要素属性质检结果/// </summary>public class CheckPropertyResult{/// <summary>/// OBJECTID/// </summary>[JsonProperty("objectid")]public int ObjectID { get; set; }/// <summary>/// 字段检查结果/// </summary>[JsonProperty("fields")]public List<string> FieldInfo { get; set; }}/// <summary>/// 属性质检结果/// </summary>public class CheckFieldsResponseBody{/// <summary>/// 图层/// </summary>[JsonProperty("layer")]public string Layer { get; set; }/// <summary>/// 质检结果/// </summary>[JsonProperty("info")]public List<CheckPropertyResult> Information { get; set; }}
}

调用时，以宗地质检为例：

                            {foreach (var aFeature in item.Feature){object oOid = null;if (!aFeature.Properties.TryGetValue("OBJECTID", out oOid))throw new Exception(string.Format("图层 {0} 存在OBJECTID有误的要素", item.Layer));int nOid = System.Convert.ToInt32(oOid);CheckPropertyResult aCheckPropResult = new CheckPropertyResult() { ObjectID = nOid, FieldInfo = new List<string>() { } };{List<string> lsNotNullFields = new List<string>() { "QXDM", "ZDTZM", "ZL", "DZWTZM", "QLR", "MJDW" };Dictionary<string, object> dict = new Dictionary<string, object>() { };foreach (var field in lsNotNullFields){object oValue = null;if (!aFeature.Properties.TryGetValue(field, out oValue))throw new Exception(string.Format("未能获取图层 {0} 的OBJECTID为 {1} 的要素的 {2} 字段值", item.Layer, nOid, field));dict.Add(field, oValue);}CheckFieldValue aCheck = new CheckFieldValue(dict);aCheck.RuleNotNullable();aCheckPropResult.FieldInfo.AddRange(aCheck.GetResult());}{for (int n = 0; n < 3; n++){string sFieldName = null;if (0 == n)sFieldName = "YSDM";else if (1 == n)sFieldName = "ZDDM";elsesFieldName = "BDCDYH";object oValue = null;if (!aFeature.Properties.TryGetValue(sFieldName, out oValue))throw new Exception(string.Format("未能获取图层 {0} 的OBJECTID为 {1} 的要素的 {2} 字段值", item.Layer, nOid, sFieldName));CheckFieldValue aCheck = new CheckFieldValue(sFieldName, oValue);if (0 == n)aCheck.RuleNullOrFixedLengthDigit(10);else if (1 == n)aCheck.RuleNullOrFixedLength(19);elseaCheck.RuleNullOrFixedLength(28);aCheckPropResult.FieldInfo.AddRange(aCheck.GetResult());}}{for (int n = 0; n < 2; n++){string sFeatureCode = (0 == n) ? "ZDTZM" : "DZWTZM";object oValue = null;if (!aFeature.Properties.TryGetValue(sFeatureCode, out oValue))throw new Exception(string.Format("未能获取图层 {0} 的OBJECTID为 {1} 的要素的 {2} 字段值", item.Layer, nOid, sFeatureCode));string sResult = 0 == n ? ParcelCheckFieldValue.CheckParcelFeatureCode(sFeatureCode, oValue) : ParcelCheckFieldValue.CheckFixedThingFeatureCode(sFeatureCode, oValue);if (!string.IsNullOrEmpty(sResult))aCheckPropResult.FieldInfo.Add(sResult);}}aResponseBody.Information.Add(aCheckPropResult);}}

若传入的参数为如下结构的List<CheckFieldsRequestBody>类型的param对象，内容为：
