            string connectionString = "Driver={0};Server={1};Database={2};UID={3};PWD={4};Port={5};SSL=true;Sslmode=Require";

            connectionString = string.Format(connectionString,
                driver,

                endpointPort);

            return connectionString;
        }

安装32位驱动程序

https://s3.amazonaws.com/redshift-downloads/drivers/AmazonRedshiftODBC32-1.3.1.1000.msi

并用.替换字符串驱动程序

string driver ="{Amazon Redshift(x86)}";
