I am trying to get describe information about an sObject similar to this:

public Map<String, Schema.SObjectField> fieldMap{get;set;} 
fieldMap=Schema.sObjectType.Lead.fields.getMap();

However, I want to substitute my own String variable "Field" instead of "LEAD" which is Standard object name.

myString='Schema.sObjectType.' + Field+ '.fields.getMap();';       
fieldMap = myString;   

Error Message : : Illegal assignment from String to MAP<String,Schema.SObjectField>

So Is there any Conversion Method for String to Map ? Or Any Suggestions where I can easily assign myString in fieldMap ?

I think this should work

  Map<String,Schema.SObjectType> gd = Schema.getGlobalDescribe();
                    Schema.SObjectType sobjType = gd.get(Field);
                    Schema.DescribeSObjectResult r = sobjType.getDescribe();
                    Map<String,Schema.SObjectField> M = r.fields.getMap();
                    fieldMap=M;
