将参数绑定到 Windows Workflow 实例& 忽略未使用的

我在 Dictionary 中有一堆命名值参数，我想将它们传递到不同的工作流程中。问题是每个工作流程只需要字典中属性的子集，并且我事先不知道哪个工作流程需要哪些属性。

问题是，当我使用要绑定的字典调用 WorkflowRuntime.CreateWorkflow 时，它失败并显示：

The activity '<workflow name>' has no public writable property named '<property name>'

我知道这意味着什么。工作流中的属性未定义，因为此特定工作流不需要该特定属性（其他工作流可能）。

无论如何，是否可以将字典绑定到工作流属性，并忽略工作流中未定义的属性？

原文

I have a bunch of named value parameters in a Dictionary<string, object>, which I want to pass into different workflows. The catch is that each workflow will only need a subset of the properties in the dictionary, and I don't know beforehand which workflow needs which properties.

The problem is that when I call WorkflowRuntime.CreateWorkflow with the dictionary to bind with, it fails with:

The activity '<workflow name>' has no public writable property named '<property name>'

I know what this means. The property in the workflow is not defined because this particular workflow does not need that particular property (other workflows might).

Is there anyway to bind a dictionary to workflow properties, and IGNORE properties that are not defined on the workflow?

为什么不将字典传递到工作流程实例中？然后，您的工作流程定义只需具有该字典的属性即可。

var inputs = Dictionary<string, YOUR_CUSTOM_TYPE>();
// ...
// fill your dictionary according to the context
// ...
var inputParams = new Dictionary<string, object>();
inputParams["WF_PROP_NAME"] = inputs;
var wfInstance = wfRuntime.CreateWorkflow(WF_TYPE, inputParams);

这样，您的工作流程只需从字典中获取感兴趣的字典项目。

Why don't you pass your dictionary into the workflow instances? Your workflow definitions then just have to have a property for that dictionary.

var inputs = Dictionary<string, YOUR_CUSTOM_TYPE>();
// ...
// fill your dictionary according to the context
// ...
var inputParams = new Dictionary<string, object>();
inputParams["WF_PROP_NAME"] = inputs;
var wfInstance = wfRuntime.CreateWorkflow(WF_TYPE, inputParams);

This way your workflows just get the dictionary items of interest from the dictionary.
