本文介绍了计算数组中的重复项的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 我正在尝试将AutoCAD属性块提取为excel Excel输出 [ ^ ] My问题是如何计算数组中重复的项目并将它们添加到新列 我尝试过: 列表< object []> rooms = new List< object []>(); using(var tr = db.TransactionManager.StartTransaction()) { foreach(SelectedObject in psr.Value) { BlockReference bref =(BlockReference) tr.GetObject(so.ObjectId,OpenMode.ForRead); Autodesk.AutoCAD.DatabaseServices.AttributeCollection attcoll = bref.AttributeCollection; object [] info = new object [4]; foreach(attcoll中的ObjectId id) { AttributeReference atref =(AttributeReference)tr.GetObject(id,OpenMode.ForRead); if(atref.Tag ==ROOM) { info [0] = atref.TextString; } if(atref.Tag ==ROOMID) { info [1] = atref.TextString; } if(atref.Tag ==ROOMAREA) { info [2] = atref.TextString; } if(!rooms.Contains(info)) { rooms.Add(info); } } } tr.Commit(); } 解决方案 而不是 List< object []> 我使用词典 [ ^ ]。 字典< string,int> myCounter = new Dictionary< string,int>(); 使用( var tr = db.TransactionManager.StartTransaction()) { foreach (SelectedObject so in psr.Value) { BlockReference bref =(BlockReference)tr.GetObject(so.ObjectId,OpenMode.ForRead); Autodesk.AutoCAD.DatabaseServices.AttributeCollection attcoll = bref.AttributeCollection; foreach (ObjectId id in attcoll) { AttributeReference atref =(AttributeReference)tr.GetObject(id,OpenMode.ForRead); if (atref.Tag.Contains( ROOM)) if (!myCounter.ContainsKey(atref.TextString)) { myCounter。添加(atref.TextString, 1 ); } else { myCounter [atref.TextString] + = 1 ; } } } } // Dictionary对象包含具有出现次数的唯一数据 Console.WriteLine( Key | Count); foreach ( var k in myCounter.Keys) { Console.WriteLine( {0} | {1} ,k,myCounter [k]); } 上面的代码应该返回如下内容: 键|数 ROOM | 5 ROOMID | 10 ROOMAREA | 15 I'm trying to extract AutoCAD attribute block to excelExcel Output[^]My question is how to count duplicated items in array and add them to new columnWhat I have tried:List<object[]> rooms = new List<object[]>(); using (var tr = db.TransactionManager.StartTransaction()) { foreach (SelectedObject so in psr.Value) { BlockReference bref = (BlockReference)tr.GetObject(so.ObjectId, OpenMode.ForRead); Autodesk.AutoCAD.DatabaseServices.AttributeCollection attcoll = bref.AttributeCollection; object[] info = new object[4]; foreach (ObjectId id in attcoll) { AttributeReference atref = (AttributeReference)tr.GetObject(id, OpenMode.ForRead); if (atref.Tag=="ROOM") { info[0] = atref.TextString; } if (atref.Tag=="ROOMID") { info[1] = atref.TextString; } if (atref.Tag=="ROOMAREA") { info[2] = atref.TextString; } if (!rooms.Contains(info)) { rooms.Add(info); } } } tr.Commit(); } 解决方案 Instead of List<object[]> i'd use a Dictionary[^].Dictionary<string, int> myCounter = new Dictionary<string, int>();using (var tr = db.TransactionManager.StartTransaction()){ foreach (SelectedObject so in psr.Value) { BlockReference bref = (BlockReference)tr.GetObject(so.ObjectId, OpenMode.ForRead); Autodesk.AutoCAD.DatabaseServices.AttributeCollection attcoll = bref.AttributeCollection; foreach (ObjectId id in attcoll) { AttributeReference atref = (AttributeReference)tr.GetObject(id, OpenMode.ForRead); if (atref.Tag.Contains("ROOM")) if (!myCounter.ContainsKey(atref.TextString)) { myCounter.Add(atref.TextString, 1); } else { myCounter[atref.TextString] += 1; } } }}//Dictionary object contains unique data with the number of occurencesConsole.WriteLine("Key | Count");foreach(var k in myCounter.Keys){Console.WriteLine("{0} | {1}", k, myCounter[k]);}Above code should return something like this:Key | CountROOM | 5ROOMID | 10ROOMAREA | 15 这篇关于计算数组中的重复项的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 09-09 15:41
