我需要将文件扩展名关联到特定的可执行应用程序并将其值写入寄存器,所以我看到本教程: tutorial
所以我创建了一个新的Wpf应用程序,我在其中添加了这个类:
public class FileAssociation
{
// Associate file extension with progID, description, icon and application
public static void Associate(string extension,
string progID, string description, string icon, string application)
{
Registry.ClassesRoot.CreateSubKey(extension).SetValue("", progID);
if (progID != null && progID.Length > 0)
using (RegistryKey key = Registry.ClassesRoot.CreateSubKey(progID))
{
if (description != null)
key.SetValue("", description);
if (icon != null)
key.CreateSubKey("DefaultIcon").SetValue("", ToShortPathName(icon));
if (application != null)
key.CreateSubKey(@"Shell\Open\Command").SetValue("",
ToShortPathName(application) + " \"%1\"");
}
}
// Return true if extension already associated in registry
public static bool IsAssociated(string extension)
{
return (Registry.ClassesRoot.OpenSubKey(extension, false) != null);
}
[DllImport("Kernel32.dll")]
private static extern uint GetShortPathName(string lpszLongPath,
[Out] StringBuilder lpszShortPath, uint cchBuffer);
// Return short path format of a file name
private static string ToShortPathName(string longName)
{
StringBuilder s = new StringBuilder(1000);
uint iSize = (uint)s.Capacity;
uint iRet = GetShortPathName(longName, s, iSize);
return s.ToString();
}
}
然后,我将图标图像添加到项目的根目录中,然后我将这个片段:
if (!FileAssociation.IsAssociated(".akp"))
FileAssociation.Associate(".akp", "ClassID.ProgID", "akp File", "akeo.ico", @"C:\Users\Lamloumi\Desktop\MyWork\C#\App - SuiteTool\bin\x64\Debug\App - SuiteTool.exe");
但我在这一行中遇到了一个问题
Registry.ClassesRoot.CreateSubKey(extension).SetValue("", progID);
所以我需要知道
谢谢,

似乎您没有足够的权限在Windows注册表中写入 尝试添加包含内容的项目app.manifest文件:
<?xml version="1.0" encoding="utf-8"?>
<asmv1:assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv1="urn:schemas-microsoft-com:asm.v1" xmlns:asmv2="urn:schemas-microsoft-com:asm.v2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
<security>
<requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
</requestedPrivileges>
</security>
</trustInfo>
</asmv1:assembly>
或者如果应用程序必须在没有请求每个开始的管理员权限的情况下工作,则可以自我提升,如本示例所示UAC self-elevation
