C# GetConstructor() method
The GetConstructor() method in the Type class is used to obtain the specific constructor of the class represented by the current Type.
There are 4 reloads
| GetConstructor(BindingFlags, Binder, CallingConventions, Type[], ParameterModifier[]) |
| GetConstructor(BindingFlags, Binder, Type[], ParameterModifier[]) |
| GetConstructor(BindingFlags, Type[]) |
| GetConstructor(Type[]) |
Take GetConstructor(Type[]) as an example
Type[] in the formal parameters represents the required constructor parameters, order and type array of Type objects. If it is an empty parameter constructor, you can set Type[] to an empty array.
The return type is the ConstructorInfo type. An object representing a common instance constructor, if not, null.
Example code:
using System;
using ;
public class MyClass1
{
public MyClass1() { }
public MyClass1(int i) { }
public static void Main()
{
try
{
Type myType = typeof(MyClass1);
Type[] types = new Type[1];
types[0] = typeof(int);
// Get the constructor that takes an integer as a parameter.
ConstructorInfo constructorInfoObj = (types);
if (constructorInfoObj != null)
{
("The constructor of MyClass1 that takes an " +
"integer as a parameter is: ");
(());
}
else
{
("The constructor of MyClass1 that takes an integer " +
"as a parameter is not available.");
}
}
catch (Exception e)
{
("Exception caught.");
("Source: " + );
("Message: " + );
}
}

The above is personal experience. I hope you can give you a reference and I hope you can support me more.
