如何在Dynamics CRM 2016中使用ExecuteWorkflowRequest调用带参数的Action? [英] How to call Action with parameter(s) using ExecuteWorkflowRequest in Dynamics CRM 2016?

问题描述

上下文

我可以使用ExecuteWorkflowRequest成功调用操作，其中被调用操作没有参数:

I can successfully call Actions using ExecuteWorkflowRequest where the called action has no parameters:

var request = new ExecuteWorkflowRequest 
{
    EntityId = myEntityId,
    WorkflowId = myWorkFlowId,
};
service.Execute(request);

其中action是一个简单的工作流，类别为"Action". 但是，我无法使用参数调用操作.

where action is a simple workflow, with Category "Action". However I can not call Actions with parameters.

到目前为止，我已经尝试过:

string myParameter = "Hello";
var inputArgumentCollection = new InputArgumentCollection();
inputArgumentCollection.Arguments.Add("MyParameterName", myParameter);
var request = new ExecuteWorkflowRequest 
{
    EntityId = myEntityId,
    WorkflowId = myWorkFlowId,
    InputArguments = inputArgumentCollection
};
service.Execute(request);

被调用的工作流是一个类别:动作，具有可选的字符串类型输入参数"MyParameterName"

The called Workflow is a Category: Action with an optional string type input parameter called "MyParameterName"

此调用会导致一个异常:

This call causes an exception saying:

此工作流无法运行，因为父工作流提供的参数与链接的子工作流中的指定参数不匹配.

This workflow cannot run because arguments provided by parent workflow does not match with the specified parameters in linked child workflow.

我也尝试过... 有些地方建议(没有证据)使用请求本身的Parameters集合为较早的CRM版本...虽然看起来很丑和/或错误，但我还是拍了一张，但没有成功:

I've also tried... Some places recommend (with no proof) for older CRM versions using the Parameters collection of the request itself... although it seems ugly and/or wrong, I gave it a shoot, with no success:

request.Parameters.Add("MyParameter", myParameter);

以

无法识别的请求参数:MyParameter

Unrecognized request parameter: MyParameter

问题

如何使用ExecuteWorkflowRequest通过API调用提供参数的参数化操作?

How can I call my parametrized Action providing parameters via API using ExecuteWorkflowRequest?

推荐答案

ExecuteWorkflowRequest是为执行工作流而设计的请求，在较早版本的Dynamics CRM中尚不支持操作.无法将参数传递给它.

The ExecuteWorkflowRequest is a request that was designed for executing workflows, in an older version of Dynamics CRM not yet supporting actions. It is not possible to pass arguments to it.

相反，您需要使用必需的参数创建一个动作并按如下所示执行它:

Instead you need to create an action with the required parameters and execute it like this:

var request = new OrganizationRequest("new_myaction")
{
    // EntityReference to the target of the action (suggested custom parameter)
    ["Target"] = myEntityId,
    // Another custom parameter
    ["MyParameterName"] = "Hello"
};

service.Execute(request);

"new_myaction"是操作的逻辑名称.
