                    long RowId = myvalue
                    string json1 = "{'CommonCategory':" + chk.Items[i].Value + ",'CommonCategoryRowId':" + RowId + "}";
                    status.Text = Classforhttprequest.HttpPost("http://localhost/MyService/MetaData.svc/CommonCategoryAttributesID", json1);

这里为了将选定的Chkbox列表数据插入到DB中，我需要多次调用该服务，这等于在复选框列表中选择的项目数....我可以通过调用一次来实现我的要求并插入选定的值

从那时起......需要在DB中创建一个函数

create FUNCTION [dbo].[Splitter](@String varchar(MAX), @Delimiter char(1))       
returns @table TABLE (items varchar(MAX))       
as       
begin      
declare @idx int       
declare @slice varchar(8000)       

select @idx = 1       
    if len(@String)<1 or @String is null  return       

while @idx!= 0       
begin       
    set @idx = charindex(@Delimiter,@String)       
    if @idx!=0       
        set @slice = left(@String,@idx - 1)       
    else       
        set @slice = @String       

    if(len(@slice)>0)  
        insert into @table(Items) values(@slice)       

    set @String = right(@String,len(@String) - @idx)       
    if len(@String) = 0 break       
end   
return  end;

然后在插入SP需要这样做.......

INSERT INTO CommonCategoryAttributes
   (CommonCategoryRowId,CommonCategoryAttributeName,Priority)
   SELECT @CommonCategoryRowId, @CommonCategoryAttributeName, @Priority
   FROM dbo.[Split] (@CommonCategoryAttributeName, ',')

适用于exec CommonCategoryAttributesID 1，'Gopal，Reddy'，2;

避免多个HttpRequest插入CheckBoxList选中的数据
