Hi soniya srinivasan double [] yValues = { 15 , 60 , 12 , 13 }; string [] xValues = { "September" , "October" , "November" , "December" }; // Create a pie chart Chart chart = new Chart (); // Build a pie series Series series = new Series ( "Default" ); series . ChartType = SeriesChartType . Pie ; series [ "PieLabelStyle" ] = "Disabled" ; chart . Series . Add ( series ); // Define the chart area ChartArea chartArea = new ChartArea (); ChartArea3DStyle areaStyle = new ChartArea3DStyle ( chartArea ); areaStyle . Rotation = 0 ; Axis yAxis = new Axis ( chartArea , AxisName . Y ); Axis xAxis = new Axis ( chartArea , AxisName . X ); // Bind the data to the chart chart . Series [ "Default" ]. Points . DataBindXY ( xValues , yValues ); // Save the chart as a 300 x 200 image chart . Width = new System . Web . UI . WebControls . Unit ( 300 , System . Web . UI . WebControls . UnitType . Pixel ); chart . Height = new System . Web . UI . WebControls . Unit ( 200 , System . Web . UI . WebControls . UnitType . Pixel ); string filename = Server . MapPath ( "~" ) + "/Chart.png" ; chart .

Hi Joshi, Thanks for your answer. Please find attached code. In first thread, the invoke method is called ,it do the corresponding method.but for second invoke it will wait until first invoke completes the task.how can I call both invoke at a same time?

Hi soniya srinivasan Each thread has a separate call stack, so yes they can both be using the same method on the same object. And indeed, if needed each thread can (via recursion) call the same method on the same instance multiple times if you really want. However, what might trip you up is if you are using state in that object (instance or static fields, etc, and anything related from that state). You will need to ensure your access to any shared state gives full consideration (and presumably synchronisation) to multi-threaded access. If helpful mark as Correct Answer
