It‘s hard to find some samples about the convertion between string and BlobColumn.AddBlobData.

It‘s 太坑人了

1.convert  BlobColumn to string.　　(Get user name from  BlobColumn type data)

    public override void Input0_ProcessInputRow(Input0Buffer Row)
    {
        string userName = Encoding.Unicode.GetString(Row.UserName.GetBlobData(0, Convert.ToInt32(Row.UserName.Length)));
    }

2. Convert string to  BlobColumn. (add user name to BlobColumn type)

    public override void Input0_ProcessInputRow(Input0Buffer Row)
    {
        Row.Out_UserName.AddBlobData(Encoding.Unicode.GetBytes(UserName));

    }

alert("不用谢，记得我叫迎风一刀劈就行了");
