關於C#讀取CSV檔以及顯示中文亂碼

1.關於C#讀取CSV檔

2.以及顯示中文亂碼∼
using (StreamReader sr = new StreamReader(ytcsv))
變：using (StreamReader sr = new StreamReader(ytcsv,System.Text.Encoding.Default))

string[,] aryResult;
                using (StreamReader sr = new StreamReader(ytcsv,System.Text.Encoding.Default))
                {
                    //讀取文字檔
                    string txt = sr.ReadToEnd().Trim();
                    string[] aryStr = txt.Split('\n');//有幾"列"
                    int hight = aryStr.Length;
                    int width = aryStr[0].Split(',').Length;//有幾"行"
                    aryResult = new string[hight, width];//確定後宣告陣列大小
                    //帶值進去
                    for (int h = 0; h < hight; h++)
                    {
                        string[] arySplit = aryStr[h].Split(',');
                        for (int w = 0; w < width; w++)
                        {
                            aryResult[h, w] = arySplit[w];
                            this.Text = "H：" + hight + "-W：" + width;
                        }
                    }
                }

                //印出結果
                for (int h = 0; h <= aryResult.GetUpperBound(0); h++)
                {
                    for (int w = 0; w <= aryResult.GetUpperBound(1); w++)
