我正在使用 C# 应用程序中的 GnuPlot。我想直接从标准输出读取 GnuPlot PNG 输出,而不是保存到文件然后读取它。我的代码现在看起来像这样:
string Path = @"C:\Program Files\gnuplot\bin\gnuplot.exe";
Process GnuplotProcess = new Process();
GnuplotProcess.StartInfo.FileName = Path;
GnuplotProcess.StartInfo.UseShellExecute = false;
GnuplotProcess.StartInfo.RedirectStandardInput = true;
GnuplotProcess.StartInfo.RedirectStandardOutput = true;
GnuplotProcess.Start();
StreamWriter SW = GnuplotProcess.StandardInput;
StreamReader SR = GnuplotProcess.StandardOutput;
SW.WriteLine("set terminal pngcairo size 300,200");
foreach (LoadCaseOutput LCO in LoadCases)
{
foreach (LoadCaseOutput.MemberOutput MO in LCO.Members)
{
SW.WriteLine("plot " + MO.GenerateAFEquation(P));
MO.AFImage = Image.FromStream(SR.BaseStream);
}
}
SW.WriteLine("exit");
GnuplotProcess.Close();
现在这似乎停滞在 Image.FromStream() 行。怎么了?
