AWS S3 putobject with public read permissions - .Net SDK

Question

I am using the .Net SDK for AWS.

I want to put a file into S3 and make its content readable by public, I see that I can use the "Grants" property in order to do this, however I cant find the value inputs in the online documentation for some of the fields.

var request = new PutObjectRequest()
{
BucketName = "some-bucket",
Key = fileName,
FilePath = filePath,
StorageClass = new S3StorageClass("REDUCED_REDUNDANCY"),
ContentType = "text/csv",
Grants = new List<S3Grant>() {
new S3Grant() {
Grantee = new S3Grantee()
{
CanonicalUser = "Everyone",
DisplayName = "Everyone"
},
Permission = new S3Permission("open/download")}}
};

In the above request:

1) The grantee "Everyone" is just my guess, what should be the valid value there?

2) For S3Permission what is the valid value equivalent to my guess of "open/download"?

I understand I have to make list permission open to public at the bucket level as well, I can do everything via the console, I just can't seem to find the valid API request parameters.

Re-posting it here for ease:

http://docs.aws.amazon.com/sdkfornet1/latest/apidocs/html/T_Amazon_S3_Model_S3CannedACL.htm

var request = new PutObjectRequest()
{
    BucketName = "some-bucket",
    Key = fileName,
    FilePath = filePath,
    StorageClass = new S3StorageClass("REDUCED_REDUNDANCY"),
    ContentType = "text/csv",
    CannedACL = S3CannedACL.PublicRead
};

This would upload the file, and set it with Public Read permissions.

In case you get "Access Denied" errors, make sure you have "PutObjectAcl" permission in your IAM policy.
