Question

私は

[ 
    { 
     name: 'Apple', 
     data: [ 
      { name: 'April', y: 35 }, 
      { name: 'June', y: 1 } 
     ] 
    }, 
    { 
     name: 'Orange', 
     data: [ 
      { name: 'April', y: 7 }, 
      { name: 'July', y: 11 }, 
      { name: 'June', y: 7 }, 
      { name: 'May', y: 6 } 
     ] 
    }, 
    { 
     name: 'Mango', 
     data: [ 
      { name: 'July', y: 1 } 
     ] 
    }, 
    { 
     name: 'Grapes', data: [ 
      { name: 'June', y: 1 } 
     ] 
    }, 
    { 
     name: 'Cheery', 
     data: [ 
      { name: 'June', y: 1 } 
     ] 
    } 
]; 

は、だから私は、このコードは形式

var mdata1 = new TrackDataEntities1().spdatasumry(frDate, to_Date, RegNo) 
      .Select(s => new { s.Name }).ToArray().Distinct(); 

foreach (var c in mdata1) { 
    voil.Add(c.Name); 
} 

var sdata = new TrackDataEntities1().spdatasumry(frDate, to_Date, RegNo) 
      .Select(s => new {s.Name,s.Month,s.total }).ToArray(); 

string data2 = "["; 
foreach(string vo in voil) { 
    data2 += "{name:'" + vo + "',"; 
    data2 += "data:["; 

    foreach(string mo in vmonths) { 
     decimal tv = 0; 

     try { 
      tv = sdata.Single(t => t.Month == mo && t.Name == vo).total; 
     } catch { 
      tv = 0; 
     } 

     if (tv > 0) { 
      data2 += "{name:'" + mo + "',y:" + tv + "},"; 
     } 
    } 
    data2 += "]},"; 
} 

data2 = data2.Remove(data2.Length - 1); 
data2 += "]"; 

超えるが以下にこの

ようなコード・ショー形式上必要な取得しようと、このフォーマットを取得しようコードコンマはその部分{name:'June',y:1},]},であり私は正しい形式

を取得するために、第二の最後の ,]},コンマを削除したいです10

"[{name:'Apple',data:[{name:'April',y:35},{name:'June',y:1},]}, 
{name:'Orange',data:[{name:'April',y:7},{name:'July',y:11},{name:'June',y:7},{name:'May',y:6},]}, 
{name:'Mango',data:[{name:'July',y:1},]}, 
{name:'Grapes',data:[{name:'June',y:1},]}, 
{name:'Cheery',data:[{name:'June',y:1},]}]" 

Answer 1

あなたは間違っている各ノードで、余分なコンマを追加しています。最後のノードで次のようなカンマを追加する必要はありません。

var i = 0; 
foreach(string vo in voil) { 
    data2 += "{name:'" + vo + "',"; 
    data2 += "data:["; 

    var j = 0; 
    foreach(string mo in vmonths) { 
     decimal tv = 0; 

     try { 
      tv = sdata.Single(t => t.Month == mo && t.Name == vo).total; 
     } catch { 
      tv = 0; 
     } 

     if (tv > 0) { 
      j++; 
      if(vmonths.Length == j){ 
       data2 += "{name:'" + mo + "',y:" + tv + "}"; 
      }else{ 
       data2 += "{name:'" + mo + "',y:" + tv + "},"; 
      } 
     } 
    } 
    i++; 

    if(voil.Length == i){ 
     data2 += "]}"; 
    }else{ 
     data2 += "]},"; 
    } 
}
