我想在 asp.net 4 中使用 zedgraph。但我得到以下错误：
System.IO.DirectoryNotFoundException：
Could not find a part of the path C:\Users\stn-1\Desktop\ZedGraphWebAp1_CompiledSite8 \ZedGraphImages\ZedGraphWeb1fc6eb2c0-023a-4818-bff9-9c957971af4b.png. 在 System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) 在 System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs , String msgPath, Boolean bFromProxy, Boolean useLongPath) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share) at ZedGraph.Web.ZedGraphWeb.Render(HtmlTextWriter output)
我使用下面的代码：
protected void ZedGraphWeb1_RenderGraph(ZedGraphWeb webObject, System.Drawing.Graphics g, MasterPane pane)
{
GraphPane myPane = pane[0];
myPane.Title.Text = "Title";
myPane.XAxis.Title.Text = "X axis label";
myPane.YAxis.Title.Text = "Y axis label";
PointPairList list1 = new PointPairList();
for (int i = 0; i < 10; i++)
{
double x = Convert.ToDouble(i);
double y = x * x;
list1.Add(x, y);
}
string textForLegend = "x-squared";
myPane.CurveList.Clear();
LineItem myCurve = myPane.AddCurve(textForLegend,
list1, Color.Red, SymbolType.Diamond);
myCurve.Symbol.IsVisible = true;
}
