DayDreamInGIS 之 ArcGIS Pro二次开发 图层属性中换行符等特殊字符替换

不超限2024-03-02 14:51

具体参考ArcMap中类似的问题，本帖开发一个ArcGISPro版的工具

1.基础库部分

插件开发，经常需要处理图层与界面的交互。基础库把常用的交互部分做了封装，方便之后的重复使用。

（1）下述类定义了数据存储结构，主要用于保存Combox中的label与值。比如，Name_Index类，用于保存名称-数值索引，Name_Layer类，用于保存图层名-图层

cs 复制代码 
using ArcGIS.Desktop.Mapping;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace GISCommonHelper
{
    /// <summary>
    /// 名称与索引，用于数据绑定时界面的显示,适用于字段名与索引，图层名与索引等
    /// </summary>
    public class Name_Index
    {
        public string name { get; set; }
        public int index { get; set; }

        public Name_Index(string name, int index)
        {
            this.name = name;
            this.index = index;
        }
    }

    /// <summary>
    /// 字段名与假名
    /// </summary>
    public class Name_AliasName
    {
        public string name { get; set; }
        public string alias_name { get; set; }
        public Name_AliasName(string name, string alias_name)
        {
            this.name = name;
            if (string.IsNullOrEmpty(this.alias_name))
            {
                this.alias_name = alias_name;
            }
            else
            {
                this.alias_name = name;
            }
        }
    }

    /// <summary>
    /// 图层名与图层
    /// </summary>
    public class Name_Layer
    {
        public string Name { get; set; }
        public Layer layer { get; set; }
        public Guid id { get; set; }

        public Name_Layer(string name, Layer layer)
        {
            this.Name = name;
            this.layer = layer;
            this.id = Guid.NewGuid();
        }
    }

    public class name_obj
    {
        public string name { get; set; }
        public object obj { get; set; }
        public Guid id { get; set; }
        public string tp { get; set; }

        public name_obj() { }

        public name_obj(string name, object obj, string tp)
        {
            this.name = name;
            this.obj = obj;
            this.tp = tp;
            this.id = Guid.NewGuid();
        }
    }
}

（2）下述代码实通过静态扩展的方式，扩展WPF 中Combox组件，新增方法

setLyrlist<T>，通过数据绑定的形式设置Combox的Items集合，通过提供一个Map对象，以及泛型类型T

setDftLyr，通过lambda表达式的方式，配置Combox默认的选中值。

通过该扩展类， Combox.SelectedValue 即可获取该下拉框的选中对象

cs 复制代码 
using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Controls;
using ArcGIS.Desktop.Mapping;

namespace GISCommonHelper
{
    public static class CartoLyrHelper
    {
        /// <summary>
        /// 设置图层
        /// </summary>
        /// <typeparam name="T"></typeparam>
        /// <param name="cmb"></param>
        /// <param name="map"></param>
        public static void setLyrlist<T>(this ComboBox cmb,Map map) where T:Layer
        {
            var lyrlist = map.GetLayersAsFlattenedList().OfType<T>().ToList();
            List<Name_Layer> nlist = new List<Name_Layer>();
            lyrlist.ForEach(item =>
            {
                Layer l = (Layer)item;
                nlist.Add(new Name_Layer(l.Name, l));

            });
            cmb.ItemsSource = nlist;
            cmb.DisplayMemberPath = "Name";
            cmb.SelectedValuePath = "layer";
        }

        /// <summary>
        /// 设置下拉集合
        /// </summary>
        /// <typeparam name="T"></typeparam>
        /// <param name="cmb"></param>
        /// <param name="map"></param>
        /// <param name="clause"></param>
        public static void setLyrlist<T>(this ComboBox cmb,Map map,Func<Layer,bool> clause) where T : Layer
        {
            cmb.setLyrlist<T>(map);
            cmb.setDftLyr(clause);
        }

        /// <summary>
        /// 设置默认选中的图层
        /// </summary>
        /// <param name="cmb"></param>
        /// <param name="clause"></param>
        public static void setDftLyr(this ComboBox cmb,Func<Layer,bool> clause)
        {
            List<Name_Layer>? lyrlist = new List<Name_Layer>();
            if (cmb.ItemsSource == null)
            {
                return;
            }
            else
            {
                lyrlist = cmb.ItemsSource as List<Name_Layer>;
            }
            for (int i = 0; i < lyrlist.Count; i++)
            {
                var item = lyrlist[i].layer;
                if (clause(item))
                {
                    cmb.SelectedIndex = i;
                }
            }
        }
    }

}
