我的C＃类将创建一个GUI，它接收csv文件并相应地绘制线图。目前，我的图表是使用GUI文件对话框绘制和保存的。
我现在要做的是使用命令行读取，绘制并保存图形（不需要GUI）。
我可以知道如何使用“-f”标志调用我的Read和Plot类（文件路径，可以有多个csv文件）并使用“-o”标志保存绘制的图形（输出文件路径，仅生成1个文件）？
感谢。

您可以使用命令解析器库。命令行解析器（http://commandline.codeplex.com/）非常易于使用。
[Option("f", "input", Required = true]
public string InputFile { get; set; }
[Option("o", "output", Required = true]
public string OutputFile { get; set; }

如果您正在寻找简单的东西，那么您可以获得一个循环并获得如下值：
string f=null;
string o=null;
for (var i = 0; i < args.Length; i++)
{
if (args[i] == "-f") { f = args[i + 1]; }
else if (args[i] == "-o") { o = args[i + 1]; }
}
if (f != null)
{
}
if (o != null)
{
}

您可以使用：
