Over the past few days, some users have informed us that they are encountering a type not found constructor.

This is because you are using the Activator.CreateInstance
overload, which accepts a powerful array of objects that should contain almost any list of constructor parameters. In a different style, it tries to find a shoe constructor StateLog
that has 16 parameters instead of just one . This is compiled from a covariance table.
Activator.CreateInstance (typeof (T), lines)
Since lines
is a []
string, it thinks you want to trust the covariance to convert it to object []
> conveniently , which means that the compiler sees the device as follows:
Activator.CreateInstance (lines typeof (T), Method (object []))
Then you’re looking for a constructor that has lines.Length
parameters, all of type string
.
StateLog class public StateLog (string [] string) ... Community StateLog (line a, line b, line c) ...
Calling Activator.CreateInstance (typeof (StateLog), newline [] "a", "b", "c")
calls the constructor (with one and three parameters), consumed by the first.
What you are actually looking for is to efficiently pass all
strings as the first element of an array:
variable criterion = new object [1];parameter [0] = strings;Activator.CreateInstance (parameter type (T))
list.Add ((T) Activator.CreateInstance (typeof (T), most recent object lines []));
Your
computation style does not contain It is a constructor without parameters. You must pass constructor parameters using the PrivateObject
[^]:
constructor
The chain expression is "5 * 10-18 / (3 + 19)";PrivateObject obj = new PrivateObject ( type (calculation), new [], typeof (string) new [] reflection);
You are also trying to call the sendNumberToCalculation
method with a specific parameter of type PolishNotation
, but most of the methods have no parameters. You must remove the second argument after calling Invoke
:
double current = Convert.ToDouble (obj.Invoke ("sendNumberToCalculation"));

Hello
I am using Dot-Net-Framework 2.0 …. I am bold and underline errors …
Word of error
There is no parameterless constructor defined for this part. Don’t run C # or the type constructor.

Help, please, I struggle for a long time …. Thanks in advance …
/// Code fix ….
Assembly a = Assembly.LoadFrom (Application.StartupPath + ” XYS.exe”);
Enter mytypes = a.GetType (“XYS.Profiler”);
Obj is equal to Activator.CreateInstance (mytypes, new object [] true);
mytypes.InvokeMember (“CheckForExistingService”, BindingFlags.Default | BindingFlags.InvokeMethod, zero, obj, new object [] sPortNumber);
