==Call GetConstructor to get the constructor==

<source lang="csharp">
using System;
using System.Text;
using System.Reflection;
class MainClass
{
public static StringBuilder CreateStringBuilder()
{
Type type = typeof(StringBuilder);
Type[] argTypes = new Type[] { typeof(System.String), typeof(System.Int32) };
ConstructorInfo cInfo = type.GetConstructor(argTypes);
object[] argVals = new object[] { "Some string", 30 };
StringBuilder sb = (StringBuilder)cInfo.Invoke(argVals);
return sb;
}
}
</source>

==Get parameter information by using ConstructorInfo and ParameterInfo==

<source lang="csharp">
using System;
using System.Collections;
using System.Reflection;
public class MainClass{
public static void Main() {
Assembly LoadedAsm = Assembly.LoadFrom("yourName");
Console.WriteLine(LoadedAsm.FullName);
Type[] LoadedTypes = LoadedAsm.GetTypes();
if (LoadedTypes.Length == 0) {
Console.WriteLine("\tNo Types!");
} else {
Console.WriteLine("\tFound Types:");
foreach (Type t in LoadedTypes) {
if (t.IsPublic && !t.IsEnum && !t.IsValueType) {
Console.WriteLine("Type: {0}", t.FullName);
PrintConstructorInfo(t);
}
}
}
}
private static void PrintConstructorInfo(Type t) {
ConstructorInfo[] ctors = t.GetConstructors();
foreach (ConstructorInfo c in ctors) {
ParameterInfo[] pList = c.GetParameters();
if (pList.Length == 0) {
if (c.IsStatic)
Console.WriteLine("\tFound static Constructor.");
else
Console.WriteLine("\tFound default consructor.");
} else {
Console.WriteLine("\tConstructor:");
foreach (ParameterInfo p in pList) {
Console.WriteLine("\t\t{0} {1}", p.ParameterType.FullName,p.Name);
}
}
}

==Invoke in Constructor through ConstructorInfo==

<source lang="csharp">

using System;
using System.Text;
using System.Reflection;
class MainClass {
public static void Main() {
Type type = typeof(StringBuilder);
Type[] argTypes = new Type[] { typeof(System.String), typeof(System.Int32) };
ConstructorInfo cInfo = type.GetConstructor(argTypes);
object[] argVals = new object[] { "Some string", 30 };
StringBuilder sb = (StringBuilder)cInfo.Invoke(argVals);
Console.WriteLine(sb.ToString());

}
}
