i have made a MYSQL_ECMA.dll (using sql_ecma.dll) but when i create that ECMA it is unable to create get_schemafrom my sql

Database=test

table=HR

 public Schema GetSchema(KeyedCollection<string, ConfigParameter> configParameters)
        {
            
            Microsoft.MetadirectoryServices.SchemaType personType = Microsoft.MetadirectoryServices.SchemaType.Create("Person", false);

            myServer = configParameters["Server"].Value;
            myDB = configParameters["Database"].Value;
            myTable = configParameters["Table"].Value;

           DataSet myData = this.MYSQLSchema(myServer, myDB, myTable);
            
            
           
            string[] MYSQLSchema =new string[myData.Tables["Columns"].Rows.Count];

            for (int i = 0; i <= myData.Tables["Columns"].Rows.Count - 1; i++)
            {

               
                MYSQLSchema[i]=myData.Tables["Columns"].Rows[i].ItemArray.GetValue(0).ToString().Trim();
               

                string myattrib=MYSQLSchema[i];

                if (myattrib == "EmployeeID")
                {
                    personType.Attributes.Add(SchemaAttribute.CreateAnchorAttribute(myattrib, AttributeType.String));
                }

                else
                {
                    personType.Attributes.Add(SchemaAttribute.CreateSingleValuedAttribute(myattrib, AttributeType.String));
                }

            }

            Schema schema = Schema.Create();
            schema.Types.Add(personType);

            return schema;
        }
