Question

How to find if given string is Built In Types, which are aliases of predefined types in the System Namespace.
Ex: 1

Input = "System.Int32" (this is string)
OutPut : True(indicating it's Built-In Name)

Ex :2

Input = "xxx"
Output = False(indicating it's not Built-In Type name)

Any suggestion regarding this is highly appreciated.

Thanks in advance

Answer 1

public bool IsBuiltInType(string typeName)
{
  return Type.GetType(typeName, false) != null; 
}

I think this is what your looking for.

  IsBuiltInType("System.Int32");

The above returns true, as it finds the System.Int32 type – You can also throw an error if it doesn’t find the specified type.
