我需要在应用程序图标的本地计算机上获取已安装程序的列表.下面是用于获取已安装程序和已安装目录路径列表的代码段.
/// <summary>
/// Gets a list of installed software and,if known,the software's install path.
/// </summary>
/// <returns></returns>
private string Getinstalledsoftware()
{
//Declare the string to hold the list:
string Software = null;
//The registry key:
string SoftwareKey = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
using (RegistryKey rk = Registry.LocalMachine.OpenSubKey(SoftwareKey))
{
//Let's go through the registry keys and get the info we need:
foreach (string skName in rk.GetSubKeyNames())
{
using (RegistryKey sk = rk.OpenSubKey(skName))
{
try
{
//If the key has value,continue,if not,skip it:
if (!(sk.GetValue("DisplayName") == null))
{
//Is the install location known?
if (sk.GetValue("InstallLocation") == null)
Software += sk.GetValue("DisplayName") + " - Install path not known\n"; //Nope,not here.
else
Software += sk.GetValue("DisplayName") + " - " + sk.GetValue("InstallLocation") + "\n"; //Yes,here it is...
}
}
catch (Exception ex)
{
//No,that exception is not getting away... :P
}
}
}
}
return Software;
}
现在的问题是我如何获得已安装的应用程序图标？
提前致谢.
解决方法
为了确定它是否是更新,将有一个名为IsMinorUpgrade的密钥.这存在并设置为1以进行更新.如果它为0或不存在,那么它不是更新.
VB：
Public Function IconFromFilePath(filePath As String) As Icon
Dim result As Icon = Nothing
Try
result = Icon.ExtractAssociatedIcon(filePath)
Catch ''# swallow and return nothing. You could supply a default Icon here as well
End Try
Return result
End Function
C#：
public Icon IconFromFilePath(string filePath)
{
Icon result = null;
try {
result = Icon.ExtractAssociatedIcon(filePath);
} catch { }
return result;
}
