Convert a type pulled from assemblies back to an existing class

API

I find a class in the data section of my API by its name, using Assemblies, and I convert it to a type, where I can add values to its properties.

Now I need to convert it process it in a CRUD type API - which won't take the type (it uses a generic TEntity).

This is how I get it - how do I convert it?

public Type importClass { get; set; }
protected virtual IList<Assembly> Assemblies
        {
            get
            {
                return new List<Assembly>()
                {
                    {
                        Assembly.Load("EdenAPI.Data")
                    }
                };
            }
        }

public CSVMatch(string className)
        {
            _className = className;
            foreach (var assembly in Assemblies) {
                var classes = assembly.ExportedTypes.Where(c => c.Name == className);
                if (classes != null)
                    importClass = class[0];
                        
                    }

            }

What I have tried:

I've tried a generic handler which didn't accept the type
