    static string ConvertToJson()
    {
        lineChartClass c = new lineChartClass();

        double[] json = new double[4];

        //Array.Copy(c.piedata(), json, 4);
        c.piedata().CopyTo(json, 0);

        List<ChartItem> chartItems = new List<ChartItem>();

        chartItems.Add(new ChartItem() { Name = "Low", Data1 = json[0].ToString() });
        chartItems.Add(new ChartItem() { Name = "Moderate", Data1 = json[1].ToString() });
        chartItems.Add(new ChartItem() { Name = "Critical", Data1 = json[2].ToString() });
        chartItems.Add(new ChartItem() { Name = "High", Data1 = json[3].ToString() });
        string result = new JavaScriptSerializer().Serialize(chartItems);
        //result = "{ name: "Low", data1: " + json[0] + "}" + ",{ name: "Moderate", data1: " + json[1] + "}" + ",{ name: "Critical", data1: " + json[2] + "}" + ",{ name: "High", data1: " + json[3] + "}";

I had this.. fixed it.. thought I'd share

if you right click the .asmx file and select view markup you'll see it still says

<%@ WebService Language="C#" CodeBehind="MyService.asmx.cs" Class="MyProject.Service1" %>

maybe not Service1.. but won't be the class you've just made

<%@ WebService Language="C#" CodeBehind="MyService.asmx.cs" Class="MyProject.MyService" %>

save it.. try it..

worked for me..
