本文主要是介绍DayDreamInGIS 之 ArcGIS Pro二次开发 图层属性中换行符等特殊字符替换，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
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
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
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;}}}}}
2.界面部分
ProWindow
<controls:ProWindow x:Class="DayDreamInGISTool.AttrSpecialStrRemove.RemoveAttrSpecialStrFrm"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:controls="clr-namespace:ArcGIS.Desktop.Framework.Controls;assembly=ArcGIS.Desktop.Framework"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:d="http://schemas.microsoft.com/expression/blend/2008"xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"xmlns:extensions="clr-namespace:ArcGIS.Desktop.Extensions;assembly=ArcGIS.Desktop.Extensions"mc:Ignorable="d" ResizeMode="NoResize"Title="移除属性中特殊字符" Height="300" Width="300"WindowStartupLocation="CenterOwner" Loaded="ProWindow_Loaded"><controls:ProWindow.Resources><ResourceDictionary><ResourceDictionary.MergedDictionaries><extensions:DesignOnlyResourceDictionary Source="pack://application:,,,/ArcGIS.Desktop.Framework;component\Themes\Default.xaml"/></ResourceDictionary.MergedDictionaries></ResourceDictionary></controls:ProWindow.Resources><Grid Name="RootGrid"><Label Content="图层" HorizontalAlignment="Left" Margin="12,8,0,0" VerticalAlignment="Top"/><ComboBox Name="cmbLayer" HorizontalAlignment="Left" Margin="51,10,0,0" VerticalAlignment="Top" Width="229" SelectionChanged="cmbLayer_SelectionChanged"/><GroupBox Header="待移除特殊字符" HorizontalAlignment="Left" Margin="12,41,0,0" VerticalAlignment="Top" Height="101" Width="268" Name="ToBeRemovedGroup"><Grid Height="90" Margin="0,0,0.2,-0.4" VerticalAlignment="Top"><CheckBox Name="chkEnter" IsChecked="True" Content="换行符 \r\n" HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top"/><CheckBox Name="chkA" Content="响铃 \a" IsChecked="True" HorizontalAlignment="Left" Margin="142,10,0,0" VerticalAlignment="Top" RenderTransformOrigin="-0.313,0.526"/><CheckBox Name="chkF" IsChecked="True" Content="换页 \f" HorizontalAlignment="Left" Margin="10,34,0,0" VerticalAlignment="Top"/><CheckBox Name="chkT" IsChecked="True" Content="水平制表 \t" HorizontalAlignment="Left" Margin="142,34,0,0" VerticalAlignment="Top"/><CheckBox Name="chkV" IsChecked="True" Content="垂直制表 \v" HorizontalAlignment="Left" Margin="142,58,0,0" VerticalAlignment="Top" Checked="chkV_Checked"/><CheckBox Name="chkStartEndSpace" IsChecked="True" Content="首尾空格符" HorizontalAlignment="Left" Margin="10,58,0,0" VerticalAlignment="Top"/></Grid></GroupBox><Label Content="替换为" HorizontalAlignment="Left" Margin="12,151,0,0" VerticalAlignment="Top" RenderTransformOrigin="-0.155,0.477"/><TextBox HorizontalAlignment="Left" Name="txtReplace" Height="23" Margin="64,151,0,0" TextWrapping="Wrap" Text="、" VerticalAlignment="Top" Width="216"/><Button Content="确定" IsDefault="True" Name="btnOK" HorizontalAlignment="Left" Margin="49,220,0,0" VerticalAlignment="Top" Width="83" Height="30" Click="btnOK_Click"/><Button Content="取消" IsCancel="True" Name="btnCancel" HorizontalAlignment="Left" Margin="174,220,0,0" VerticalAlignment="Top" Width="83" RenderTransformOrigin="-0.557,1.094" Height="30" Click="btnCancel_Click"/><CheckBox Content="处理TOC中所有图层" Name="chkAll" HorizontalAlignment="Left" Margin="51,193,0,0" VerticalAlignment="Top"/></Grid>
