Bu evrensel bir çözüm yüklemek için gereken insanlar içindir dinamik dış referanslardan jenerik türlerini tarafından AssemblyQualifiedName
hangi montaj jenerik türdeki tüm parçaları geldiğini bilmeden,:
public static Type ReconstructType(string assemblyQualifiedName, bool throwOnError = true, params Assembly[] referencedAssemblies)
{
foreach (Assembly asm in referencedAssemblies)
{
var fullNameWithoutAssemblyName = assemblyQualifiedName.Replace($", {asm.FullName}", "");
var type = asm.GetType(fullNameWithoutAssemblyName, throwOnError: false);
if (type != null) return type;
}
if (assemblyQualifiedName.Contains("[["))
{
Type type = ConstructGenericType(assemblyQualifiedName, throwOnError);
if (type != null)
return type;
}
else
{
Type type = Type.GetType(assemblyQualifiedName, false);
if (type != null)
return type;
}
if (throwOnError)
throw new Exception($"The type \"{assemblyQualifiedName}\" cannot be found in referenced assemblies.");
else
return null;
}
private static Type ConstructGenericType(string assemblyQualifiedName, bool throwOnError = true)
{
Regex regex = new Regex(@"^(?<name>\w+(\.\w+)*)`(?<count>\d)\[(?<subtypes>\[.*\])\](, (?<assembly>\w+(\.\w+)*)[\w\s,=\.]+)$?", RegexOptions.Singleline | RegexOptions.ExplicitCapture);
Match match = regex.Match(assemblyQualifiedName);
if (!match.Success)
if (!throwOnError) return null;
else throw new Exception($"Unable to parse the type's assembly qualified name: {assemblyQualifiedName}");
string typeName = match.Groups["name"].Value;
int n = int.Parse(match.Groups["count"].Value);
string asmName = match.Groups["assembly"].Value;
string subtypes = match.Groups["subtypes"].Value;
typeName = typeName + $"`{n}";
Type genericType = ReconstructType(typeName, throwOnError);
if (genericType == null) return null;
List<string> typeNames = new List<string>();
int ofs = 0;
while (ofs < subtypes.Length && subtypes[ofs] == '[')
{
int end = ofs, level = 0;
do
{
switch (subtypes[end++])
{
case '[': level++; break;
case ']': level--; break;
}
} while (level > 0 && end < subtypes.Length);
if (level == 0)
{
typeNames.Add(subtypes.Substring(ofs + 1, end - ofs - 2));
if (end < subtypes.Length && subtypes[end] == ',')
end++;
}
ofs = end;
n--;
}
if (n != 0)
throw new Exception("Generic type argument count mismatch! Type name: " + assemblyQualifiedName);
Type[] types = new Type[typeNames.Count];
for (int i = 0; i < types.Length; i++)
{
try
{
types[i] = ReconstructType(typeNames[i], throwOnError);
if (types[i] == null)
return null;
}
catch (Exception ex)
{
throw new Exception($"Unable to reconstruct generic type. Failed on creating the type argument {(i + 1)}: {typeNames[i]}. Error message: {ex.Message}");
}
}
Type resultType = genericType.MakeGenericType(types);
return resultType;
}
Ve bu kodla test edebilirsiniz (konsol uygulaması):
static void Main(string[] args)
{
Type t1 = typeof(Task<Dictionary<int, Dictionary<string, int?>>>);
string name = t1.AssemblyQualifiedName;
Console.WriteLine("Type: " + name);
Type t2 = ReconstructType(name);
bool ok = t1 == t2;
Console.WriteLine("\r\nLocal type test OK: " + ok);
Assembly asmRef = Assembly.ReflectionOnlyLoad("System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089");
string refTypeTest = "System.Threading.Tasks.Task`1[[System.Windows.Forms.DialogResult, System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]], mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089";
Type t3 = ReconstructType(refTypeTest, true, asmRef);
Console.WriteLine("External type test OK: " + (t3.AssemblyQualifiedName == refTypeTest));
Type t4 = ReconstructType("System.Windows.Forms.DialogResult, System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089", true, asmRef);
Console.ReadLine();
}
Benimle aynı sorunu yaşayan insanlara yardımcı olmak için çözümümü paylaşıyorum (harici referanslı derlemede hem kısmen hem de bütün olarak tanımlanabilen dizeden HERHANGİ bir türü seriyi kaldırmak için - ve referanslar uygulamanın kullanıcısı tarafından dinamik olarak eklenir).
Umarım herkese yardımcı olur!
