动态数据类型在SSIS脚本任务中不起作用

Question

I declared a variable as below in script task

dynamic sqldata = Dts.Variables["User::sqldata"].Value;

When I try to click OK for script task component, error coming as below

But when I replace dynamic keyword with object or var , which works fine.

So why dynamic datatype not working in script task?

Answer 1

stumbled across query when I had this same error myself so I thought I'd share my findings. My solution was to add Microsoft.CSharp as a reference when editing the script.

1. Edit the script component in the dataflow
2. Edit the script
3. Right click on References in the Solution Explorer
4. Add the reference "Microsoft.CSharp"
5. Use it in your class - Using Microsoft.CSharp;

Hope that helps!
