在 SSIS 脚本组件内将（XML）字符串转换为 DT_NTEXT

Question

Hey there, I have quite an Issue with an huge string from a Json. I want to write it into a Nvarchar(max) Column using the Script Component.

The OutputColumn is set to DT_NTEXT and I am using:

Output0Buffer.xdata.AddBlobData(System.Text.Unicode.UTF8.GetBytes(item.x_data));

The Jsonclass Item x_data is to string:

... public string x_data { get; set; }...

The String is an XML that looks somthing like this:

"<products>\r\n <product>\r\n <set>\r\n <pindex>PKHC544</pindex>\r\n <pvarindex><PKHC544><PKHC544.O08.MF1000></pvarindex> \r\n <child>\r\n <index>ZKVXXXXD</index>\r\n <varindex><ZKVXXXXD><ZKVXXXXDD00></varindex>\r\n </child> \r\n </set>\r\n </product>\r\n</products>"

My Error message is this:

Error: 0xC0047062 at DF Load printcarrier_Orders, SC Import printcarrier_Orders [156]: System.ArgumentNullException: The string reference is not set to a string instance. Parameter name: s for Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.HandleUserException(Exception e) at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.PrimeOutput(Int32 outputs, Int32[] outputIDs, PipelineBuffer[] buffers) at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostPrimeOutput(IDTSManagedComponentWrapper100 wrapper, Int32 outputs, Int32[] outputIDs, IDTSBuffer100[] buffers, IntPtr ppBufferWirePacket)

I think I have a problem with the Encoding of this string, maybe x_data should have a different data type. All other Columns are working smoothly.

Ok got the Issue solved, I was not checking for Null references before. It is not working if it is not included
