问题描述
hi
i有这个代码来检查.net是否已安装,并且它工作得非常好
string 键;
bool data = false ;
尝试
{
key = Registry.LocalMachine.OpenSubKey( SOFTWARE)。OpenSubKey( Microsoft)。OpenSubKey( Windows)。OpenSubKey( CurrentVersion)。OpenSubKey( 卸载)。GetValue( 50727)。ToString( );
}
catch (例外)
{
}
data =(key == 50727-50727);
label1.text = 已安装;
i试图使用相同的代码更改anothor应用程序的位置,但它会结束
32bit系统
string key1;
bool data1 = false ;
尝试
{
key1 = Registry.LocalMachine.OpenSubKey( SOFTWARE)。OpenSubKey( Wow6432Node)。OpenSubKey( Microsoft)。OpenSubKey(< span class =code-string> Windows)。OpenSubKey( < span class =code-string> CurrentVersion)。OpenSubKey( 卸载 ).OpenSubKey( Mozilla Firefox 38.0.1(x86 zh-CN))。GetValue(< span class =code-string> DisplayName)。ToString();
}
catch (例外)
{
}
data1 =(key1 = = Mozilla Firefox 38.0.1(x86 zh-CN));
label10.Text = Mozilla Firefox - + data1.ToString( );
64bit系统
string key1;
bool data1 = false ;
尝试
{
key1 = Registry.LocalMachine.OpenSubKey( SOFTWARE)。OpenSubKey( Microsoft)。OpenSubKey( Windows)。OpenSubKey(< span class =code-string> CurrentVersion)。OpenSubKey( < span class =code-string>卸载)。OpenSubKey( Mozilla Firefox 38.0.1( x86 zh-CN))。GetValue( DisplayName)。ToString() ;
}
catch (例外)
{
}
data1 =(key1 = = Mozilla Firefox 38.0.1(x86 zh-CN));
label10.Text = Mozilla Firefox - + data1.ToString( );
任何想法?

感谢所有人,这解决了我的问题
检查应用程序是否安装在注册表中
< pre lang =c#> public static bool checkInstalled( string c_name)
{
string displayName;
string registryKey = @ SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall跨度>;
RegistryKey key = Registry.LocalMachine.OpenSubKey(registryKey);
if (key!= null )
{
foreach (RegistryKey子键 in key.GetSubKeyNames()。选择(keyName = > key.OpenSubKey(keyName)))
{
displayName = subkey.GetValue( DisplayName) as string ;
if (displayName!= null && displayName.Contains(c_name))
{
return true ;
}
}
key.Close();
}
registryKey = @ SOFTWARE \Wow6432Node\Microsoft \ Windows\CurrentVersion\Uninstall跨度>;
key = Registry.LocalMachine.OpenSubKey(registryKey);
if (key!= null )
{
foreach (RegistryKey子键 in key.GetSubKeyNames()。选择(keyName = > key.OpenSubKey(keyName)))
{
displayName = subkey.GetValue( DisplayName) as string ;
if (displayName!= null && displayName.Contains(c_name))
{
return true ;
}
}
key.Close();
}
返回 false ;
}
我只是简单地使用
如果(checkInstalled ( 应用程序名称))

i have this code to check if .net installed , and it work very good
string key;
bool data = false;

}
catch (Exception)
{
}
data = (key == "50727-50727");
label1.text = "installed";
i tried to used same code with change the location for anothor apps but it faild
32bit system
string key1;
bool data1 = false;
try
{
key1 = Registry.LocalMachine.OpenSubKey("SOFTWARE").OpenSubKey("Wow6432Node").OpenSubKey("Microsoft").OpenSubKey("Windows").OpenSubKey("CurrentVersion").OpenSubKey("Uninstall").OpenSubKey("Mozilla Firefox 38.0.1 (x86 en-GB)").GetValue("DisplayName").ToString();
}
catch (Exception)
{
}
data1 = (key1 == "Mozilla Firefox 38.0.1 (x86 en-GB)");
label10.Text = "Mozilla Firefox - " + data1.ToString();
64bit system
string key1;
bool data1 = false;
try
{
key1 = Registry.LocalMachine.OpenSubKey("SOFTWARE").OpenSubKey("Microsoft").OpenSubKey("Windows").OpenSubKey("CurrentVersion").OpenSubKey("Uninstall").OpenSubKey("Mozilla Firefox 38.0.1 (x86 en-GB)").GetValue("DisplayName").ToString();
}
catch (Exception)
{
}
data1 = (key1 == "Mozilla Firefox 38.0.1 (x86 en-GB)");
label10.Text = "Mozilla Firefox - " + data1.ToString();
any idea ?

thanks for all , this solved my Q
Check if application is installed in registry
public static bool checkInstalled (string c_name) { string displayName; string registryKey = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall"; RegistryKey key = Registry.LocalMachine.OpenSubKey(registryKey); if (key != null) { foreach (RegistryKey subkey in key.GetSubKeyNames().Select(keyName => key.OpenSubKey(keyName))) { displayName = subkey.GetValue("DisplayName") as string; if (displayName != null && displayName.Contains(c_name)) { return true; } } key.Close(); } registryKey = @"SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall"; key = Registry.LocalMachine.OpenSubKey(registryKey); if (key != null) { foreach (RegistryKey subkey in key.GetSubKeyNames().Select(keyName => key.OpenSubKey(keyName))) { displayName = subkey.GetValue("DisplayName") as string; if (displayName != null && displayName.Contains(c_name)) { return true; } } key.Close(); } return false; }
And I simply just call it using
if(checkInstalled("Application Name"))
