如何為表里1列數字進行標上千位符 求代碼

例如 20000000 運行后 20,000,000

就這1列 this.lblQuantity.Border.BottomColor = System.Drawing.Color.Black;
this.lblQuantity.Border.BottomStyle = DataDynamics.ActiveReports.BorderLineStyle.None;
this.lblQuantity.Border.LeftColor = System.Drawing.Color.Black;
this.lblQuantity.Border.LeftStyle = DataDynamics.ActiveReports.BorderLineStyle.None;
this.lblQuantity.Border.RightColor = System.Drawing.Color.Black;
this.lblQuantity.Border.RightStyle = DataDynamics.ActiveReports.BorderLineStyle.None;
this.lblQuantity.Border.TopColor = System.Drawing.Color.Black;
this.lblQuantity.Border.TopStyle = DataDynamics.ActiveReports.BorderLineStyle.None;
this.lblQuantity.DataField = "wQuantity";
this.lblQuantity.Height = 0.375F;
this.lblQuantity.HyperLink = null;
this.lblQuantity.Left = 2.8125F;
this.lblQuantity.Name = "lblQuantity";
this.lblQuantity.RightToLeft = true;
this.lblQuantity.Style = "text-align: center; vertical-align: top; ";
this.lblQuantity.Text = "";
this.lblQuantity.Top = 0F;
this.lblQuantity.Width = 1.125F;

数值格式化下
this.lblQuantity.DataFormatString="{0:n}";

this.lblQuantity.DataFormatString="{0:n}";
