C＃新しい関数でdatatableを使用する

Question

データシートはスプレッドシートのデータから定義され、塗りつぶされています。次に、別の関数では、そのデータテーブルにアクセスして、それらの値をテキストとして属性にキャストします。 DrawCircuits関数で同じデータテーブルをどうやって使うのですか？

public static System.Data.DataTable ReadExcelToTable(string path) 
    { 
     string connstring = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties='Excel 8.0;HDR=NO;IMEX=1';"; 
     System.Data.DataSet set = new DataSet(); 
     using (OleDbConnection conn = new OleDbConnection(connstring)) 
     { 
      conn.Open(); 
      System.Data.DataTable sheetsName = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, new object[] { null, null, null, "Table" }); 
      string firstSheetName = sheetsName.Rows[0][2].ToString(); 
      string sql = string.Format("SELECT * FROM [{0}]", firstSheetName); 
      OleDbDataAdapter ada = new OleDbDataAdapter(sql, connstring); 
      ada.Fill(set); 
      conn.Close(); 
     } 
     return set.Tables[0]; 
    } 

//this command can insert a block and fill out attributes (text) 
    [CommandMethod("DrawCircuits")] 
    public void DrawCircuits(string name, double x, double y, double z) 
    { 
     Database db = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Database; 
     using (Transaction myT = db.TransactionManager.StartTransaction()) 
     { 
      //Get the block definition 
      string blockName = name; 
      BlockTable bt = 
       db.BlockTableId.GetObject(OpenMode.ForRead) as BlockTable; 
      BlockTableRecord blockDef = 
       bt[blockName].GetObject(OpenMode.ForRead) as BlockTableRecord; 
      //Also open paper space - we'll be adding our BlockReference to it 
      BlockTableRecord ps = 
       bt[BlockTableRecord.PaperSpace].GetObject(OpenMode.ForWrite) 
                 as BlockTableRecord; 
      //Create new BlockReference, and link it to our block definition 
      Point3d point = new Point3d(x, y, z); 
      using (BlockReference blockRef = 
        new BlockReference(point, blockDef.ObjectId)) 
      { 
       //Add the block reference to paper space 
       ps.AppendEntity(blockRef); 
       myT.AddNewlyCreatedDBObject(blockRef, true); 
       //Iterate block definition to find all non-constant 
       // AttributeDefinitions           
       foreach (ObjectId id in blockDef) 
       {      
        DBObject obj = id.GetObject(OpenMode.ForRead); 
        AttributeDefinition attDef = obj as AttributeDefinition; 
        if ((attDef != null) && (!attDef.Constant)) 
        { 
         //This is a non-constant AttributeDefinition 
         //Create a new AttributeReference 
         using (AttributeReference attRef = new AttributeReference()) 
         { 
          attRef.SetAttributeFromBlock(attDef, blockRef.BlockTransform); 
// below is where I want to access the 
// datatable loaded into memory in the other 
// function. I want the att.Ref.TextString 
// value to start from row 0 column 0 of the 
// datatable        
          if (attRef.Tag == "TAG1") 
          { 
           attRef.TextString = ""; 
          } 
          if (attRef.Tag == "XXX-NNNN+") 
          { 
           attRef.TextString = ""; 
          } 
          //Add the AttributeReference to the BlockReference 
          blockRef.AttributeCollection.AppendAttribute(attRef); 
          myT.AddNewlyCreatedDBObject(attRef, true); 
         } 
        } 
       } 
      } 
      //Our work here is done 
      myT.Commit(); 
     } 
    } 

*** 8-18-2016更新！ ヘルプを使用して、DrawCircuits（）関数のパラメータを呼び出して、Excelスプレッドシートのメモリにロードしたデータテーブルを新しい関数で使用することができました。私はこれが私が達成しようとしているものにとって最良の方法だと思う。しかし、私はもう一度、このデータテーブルを私が使用しようとしているすべてのもの、Test3（）を結んでいる別の関数で使用しようとしています。すべて正常に動作し、attRef.TextString = dr.Table.Rows [1] [0] .ToString（）; DrawCircuits（）関数の文は、データテーブルの値を属性の文字列として取り込むことで正しく機能します。

問題は、別の関数Test3（）で、Test3（）のforループを取得して次の属性グループにデータテーブルの次の行を設定できないということです。すべての属性には、データテーブルの同じ行の値が設定されます。私はこれで多くの試みを自分で試みました。あなたに正しいソリューションについてのアイデアがあれば教えてください。

[CommandMethod("Test3")] 
    public void Test3() 
    { 
     string Path = SelectSpreadsheet(); 
     System.Data.DataTable table = ReadExcelToTable(Path); 

     InsertBlocks(); 
     DrawModule("AI-1756-IF16H-SHEET1"); 
     for (int i = 0; i < 8; i++) 
     { 
      DrawCircuits("AI-AIT-CIRCUIT", 24, 17 - (i * 1), 0, table.Rows[i]); 
     } 

    }

     string connstring = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties='Excel 8.0;HDR=NO;IMEX=1';";

Answer 1

public static System.Data.DataTable ReadExcelToTable(string path) 
{ 
    //Method codes 
    ... 

    // Return the data table 
    return set.Tables[0]; 
}  

public void DrawCircuits(string name, double x, double y, double z,DataTable dt) 
{ 
    ... 
    attRef.TextString = dt.Rows[0][0]; 
    ... 
} 

public DataTable ChangeDt(DataTable dt) 
{ 
    // Change dt codes 
    ... 
    // Return changed dt 
    return dt; 
} 

public void Use(DataTable dt) 
{ 
    var myDt = ChangeDt(dt); 

    for(i=0; i<=10; i++) 
    { 
     DrawCircuits("name", 1, 2, i, myDt); 
    } 
} 

またはパラメータなしでUse方法：

public void Use() 
{ 
    var dt = ReadExcelToTable("....The Path...."); 
    var myDt = ChangeDt(dt); 
    for(i=0; i<=10; i++) 
    { 
     DrawCircuits("name", 1, 2, i, dt); 
    } 
}
