本文介绍了如何在VB.NET和C#中通过使用DllImport特性调用Win32 API函数ShellExecute来启动应用程序。示例代码展示了如何设置参数以在指定路径下打开项目B。

1) vb.net

<DllImport("Shell32.dll")>

Private Shared Function ShellExecute(ByVal hwnd As IntPtr, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Integer) As Integer
End Function

Private Sub StartApplication(ByVal projname As String, ByVal arg As String)
ShellExecute(IntPtr.Zero, "Open", projname, arg, "E:\TF\sample\ProjectB\ProjectB\bin\Debug", 1)
End Sub

2)C#

[DllImport("Shell32.dll")]
private static extern int ShellExecute(
IntPtr hwnd,
string lpOperation, //多为"open"
string lpFile, //文件名称
string lpParameters, //参数
string lpDirectory, //文件路径
int nShowCmd
);
/// <summary>
/// 加载相应的应用程序
/// </summary>
private void StartApplication(string projname, string arg)
{
//ShellExecute(IntPtr.Zero, "Open", projname, arg, Application.StartupPath + @"\", 1);
ShellExecute(IntPtr.Zero, "Open", projname, arg, "E:\\TF\\sample\\ProjectB\\ProjectB\\bin\\Debug", 1);

}
