您可以通过以下两种方式之一进行操作.

You can do it in one of two ways.

第一种方法是使用string[] args并将其从Main传递到您的Form，就像这样:

The first way is to use string[] args and pass that from Main to your Form, like so:

// Program.cs
namespace MyNamespace
{
    static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main(string[] args)
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new MyForm(args));
        }
    }
}

然后在MyForm.cs中执行以下操作:

And then in MyForm.cs do the following:

// MyForm.cs
namespace MyNamespace
{
    public partial class MyForm : Form
    {
        string Title, Line1, Line2, Line3, Line4;
        public MyForm(string[] args)
        {
            if (args.Length == 5)
            {
                Title = args[0];
                Line1 = args[1];
                Line2 = args[2];
                Line3 = args[3];
                Line4 = args[4];
            }
        }
    }
}

另一种方法是使用Environment.GetCommandLineArgs()，就像这样:

The other way is to use Environment.GetCommandLineArgs(), like so:

// MyForm.cs
namespace MyNamespace
{
    public partial class MyForm : Form
    {
        string Title, Line1, Line2, Line3, Line4;
        public MyForm()
        {
            string[] args = Environment.GetCommandLineArgs();
            if (args.Length == 6)
            {
                // note that args[0] is the path of the executable
                Title = args[1];
                Line1 = args[2];
                Line2 = args[3];
                Line3 = args[4];
                Line4 = args[5];
            }
        }
    }
}

，您只需离开Program.cs原始状态，就不用string[] args.

and you would just leave Program.cs how it was originally, without the string[] args.
