Imports System.Security.Principal
Dim identity = WindowsIdentity.GetCurrent()
Dim principal = new WindowsPrincipal(identity)
Dim isElevated as Boolean = principal.IsInRole(WindowsBuiltInRole.Administrator)
If isElevated Then
MessageBox.Show("Is Admin")
End If
In VB.Net there is even a shortcut for this:
在 VB.Net 中，甚至还有一个快捷方式：
If My.User.IsInRole(ApplicationServices.BuiltInRole.Administrat??or) Then ...

Just change the app.manifest to force require administration:
只需更改 app.manifest 以强制要求管理：
Solution Explorer --> My Project --> View Windows Settings
解决方案资源管理器 --> 我的项目 --> 查看 Windows 设置
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

You can try and create a file on the system drive inside a try/catch block, and if it catches an access denied exception, then that means that the app is not running as administrator.
您可以尝试在系统驱动器上的 try/catch 块内创建一个文件，如果它捕获访问被拒绝的异常，则意味着该应用程序未以管理员身份运行。
Imports System.IO
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Try
File.Create("c://test.txt")
MessageBox.Show("Is Admin")
File.Delete("c://test.txt")
Catch ex As Exception
If ex.ToString.Contains("denied") Then
MessageBox.Show("Is Not Admin")
End If
End Try
End Sub
End Class

A version for C# 6(or later), adapted from the Visual Basicsolution posted elsewhere on this page. In the interest of general-purpose use1, here I conceive a bool-valued static property:
(using System.Security.Principal;)
一个版本的C＃6（或更高版本），改编自Visual Basic中解决此页面上的其他地方发布。在一般用途的利息1，在这里我想到一个bool-valued静态属性：
（using System.Security.Principal;）
public static bool IsAdministrator =>
new WindowsPrincipal(WindowsIdentity.GetCurrent())
.IsInRole(WindowsBuiltInRole.Administrator);
Now having shown this, one must acknowledge that @Mederic's approach does indeed seem superior, since it's unclear precisely what an app might helpfully do after presumably detecting—and reporting—that such a (presumably) critical precondition has failed. Surely it's wiser—and safer—to delegate concerns of this nature to the OS.
现在已经证明了这一点，人们必须承认@Mederic 的方法确实看起来更胜一筹，因为目前尚不清楚应用程序在可能检测到并报告这样一个（可能的）关键先决条件失败后可能会做什么有帮助。当然，将这种性质的问题委托给操作系统更明智也更安全。
1That is, eliding the "MessageBox" desiderata articulated by the OP.
1也就是说，省略MessageBox了 OP 所阐明的“ ”需求。
