我有三个EXE
带有3.5 net框架的EXE1版本
带有4.5 net框架的EXE2构建
带有4.6 NET框架的EXE3构建
我要在检测到已安装哪个.Net版本并根据该启动exe后运行exe
如果已安装3.5
运行（EXE1）
如果安装了4.5
运行（EXE2）
如果安装了4.6
运行（EXE3）
我考虑过wix的安装程序，但iexpress却没得到任何东西，所以我们怎么做呢？
还是可能的？如果是，那么如何以及如果否，那么我们可以借助第三方软件来做到这一点吗？
所以我需要一种按平台运行exe的方法，因为每个平台都有
他们自己的.Net框架
最佳答案
有两种方法：在运行该版本的exe之后，使用bath文件检测.net版本
或构建一个porogram exe依赖.net 2，此exe决定必须运行女巫文件
更新：
该示例为您提供了.net构想版本。
for.net 4及更高版本
private static void GetVersionFromRegistry()
{
// Opens the registry key for the .NET Framework entry.
using (RegistryKey ndpKey =
RegistryKey.OpenRemoteBaseKey(RegistryHive.LocalMachine, "").
OpenSubKey(@"SOFTWARE\Microsoft\NET Framework Setup\NDP\"))
{
// As an alternative, if you know the computers you will query are running .NET Framework 4.5
// or later, you can use:
// using (RegistryKey ndpKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine,
// RegistryView.Registry32).OpenSubKey(@"SOFTWARE\Microsoft\NET Framework Setup\NDP\"))
foreach (string versionKeyName in ndpKey.GetSubKeyNames())
{
if (versionKeyName.StartsWith("v"))
{
RegistryKey versionKey = ndpKey.OpenSubKey(versionKeyName);
string name = (string)versionKey.GetValue("Version", "");
string sp = versionKey.GetValue("SP", "").ToString();
string install = versionKey.GetValue("Install", "").ToString();
if (install == "") //no install info, must be later.
Console.WriteLine(versionKeyName + " " + name);
else
{
if (sp != "" && install == "1")
{
Console.WriteLine(versionKeyName + " " + name + " SP" + sp);
}
}
if (name != "")
{
continue;
}
foreach (string subKeyName in versionKey.GetSubKeyNames())
{
RegistryKey subKey = versionKey.OpenSubKey(subKeyName);
name = (string)subKey.GetValue("Version", "");
if (name != "")
sp = subKey.GetValue("SP", "").ToString();
install = subKey.GetValue("Install", "").ToString();
if (install == "") //no install info, must be later.
Console.WriteLine(versionKeyName + " " + name);
else
{
if (sp != "" && install == "1")
{
Console.WriteLine(" " + subKeyName + " " + name + " SP" + sp);
}
else if (install == "1")
{
Console.WriteLine(" " + subKeyName + " " + name);
}
}
}
}
}
}
}
并获得.net 4.5及更高版本
using System;
using Microsoft.Win32;
public class GetDotNetVersion
{
public static void Get45PlusFromRegistry()
{
const string subkey = @"SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full\";
using (RegistryKey ndpKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32).OpenSubKey(subkey))
{
if (ndpKey != null && ndpKey.GetValue("Release") != null) {
Console.WriteLine(".NET Framework Version: " + CheckFor45PlusVersion((int) ndpKey.GetValue("Release")));
}
else {
Console.WriteLine(".NET Framework Version 4.5 or later is not detected.");
}
}
}
// Checking the version using >= will enable forward compatibility.
private static string CheckFor45PlusVersion(int releaseKey)
{
if (releaseKey >= 460798) {
return "4.7 or later";
}
if (releaseKey >= 394802) {
return "4.6.2";
}
if (releaseKey >= 394254) {
return "4.6.1";
}
if (releaseKey >= 393295) {
return "4.6";
}
if ((releaseKey >= 379893)) {
return "4.5.2";
}
if ((releaseKey >= 378675)) {
return "4.5.1";
}
if ((releaseKey >= 378389)) {
return "4.5";
}
// This code should never execute. A non-null release key should mean
// that 4.5 or later is installed.
return "No 4.5 or later version detected";
}
}
// Calling the GetDotNetVersion.Get45PlusFromRegistry method produces
// output like the following:
// .NET Framework Version: 4.6.1
并通过此示例，您可以运行exe文件
using System;
using System.Diagnostics;
using System.ComponentModel;
namespace MyProcessSample
{
class MyProcess
{
public static void Main()
{
Process myProcess = new Process();
try
{
myProcess.StartInfo.UseShellExecute = false;
// You can start any process, HelloWorld is a do-nothing example.
myProcess.StartInfo.FileName = "C:\\HelloWorld.exe";
myProcess.StartInfo.CreateNoWindow = true;
myProcess.Start();
// This code assumes the process you are starting will terminate itself.
// Given that is is started without a window so you cannot terminate it
// on the desktop, it must terminate itself or you can do it programmatically
// from this application using the Kill method.
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}
}
}
}
更新2：
通过此更新，您可以在批处理文件中获得.net的最新版本。
@echo off
setlocal
@SET INSTALLUTILDIR=
@for /F "tokens=1,2*" %%i in ('reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5" /v "Version"') DO (
if "%%i"=="Version" (
SET .NetVer=%%k
)
)
@for /F "tokens=1,2*" %%i in ('reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full" /v "Version"') DO (
if "%%i"=="Version" (
SET .NetVer=%%k
)
)
ECHO The most current version of Net in use is %.NetVer%
通过此代码，您可以运行程序，但不要忘记bat文件必须位于文件夹中，exe文件在那里
start myProgram.exe
exit
