带参数c＃

Question

我有一堂课

命名空间TestLib1

public class TestLib1
{
    public IEnumerable<TestedParameter> Measure1(IEnumerable<TestedParameter> _inParameters)
    { // this is just to do something
        foreach (TestedParameter item in _inParameters)
        {
            item.Param_Description = "TestParam";
        }
        return _inParameters;
    }
}

包含

中的类

public class Acceptance_Criteria
{
    private double _lowest;
    private double _highest;
    public bool Compare(double _verifiedValue)
    {
        if ((_verifiedValue >= _lowest) && (_verifiedValue <= _highest))
        {
            return true;
        }
        else
        {
            return false;
        }
    }        
    public double Acceptance_Lowest { get =>_lowest;set =>_lowest = value; }
    public double Acceptance_Highest {get=>_highest;set =>_highest = value; }
}

public class TestedParameter : Acceptance_Criteria
{
    private string _param_Description;
    private double _value;
    private string _units;
    private bool _value_matches_acceptance_critera;
    private bool _value_checked_against_criteria;
    private string pass_fail_reason;
    public string Param_Description { get => _param_Description; set => _param_Description = value; }
    public double Value { get => _value; set => _value = value; }
    public string Units { get => _units; set => _units = value; }
    public bool Value_matches_acceptance_critera { get => _value_matches_acceptance_critera; set => _value_matches_acceptance_critera = value; }
    public bool Value_checked_against_criteria { get => _value_checked_against_criteria; set => _value_checked_against_criteria = value; }
    public string Pass_fail_reason { get => pass_fail_reason; set => pass_fail_reason = value; }
}

然后我将TestLib放在DLL中，并从其他文件中调用它：

Assembly SampleAssembly = Assembly.LoadFrom("TestLib1.dll");  
Type[] types2 = SampleAssembly.GetTypes();//e



        Type SearchedType = null;
        foreach (Type type in types2)
        {
            if (type.FullName.Contains("TestLib1.TestLib1")) { SearchedType = SampleAssembly.GetType(type.FullName); }
        }


        if (SearchedType != null)
        {
            MethodInfo Method = SearchedType.GetMethod("Measure1");
            if (Method != null)
            {
                object result = null;
                ParameterInfo[] parameters = Method.GetParameters();
                object classInstance = Activator.CreateInstance(SearchedType, null);
                if (parameters.Length == 0)
                {
                    //This works fine
                    result = Method.Invoke(classInstance, null);
                }
                else
                {
                    List<TestedParameter> parametersIn = new List<TestedParameter>();
                    TestedParameter param1 = new TestedParameter();
                    param1.Param_Description = "testparam1";             // GET NAME FROM XML
                    parametersIn.Add(param1);

                    IEnumerable<TestedParameter> enumarableList = parametersIn.AsEnumerable();

                    object[] parametersArrayx = new object[] { enumarableList };
                    object resx = Method.Invoke(classInstance, parametersArrayx.ToArray());
                    List<TestedParameter> res = (List<TestedParameter>)resx;
                }
            }



        }

当我执行Method.Invoke时 我得到例外：

  

System.ArgumentException：

     

“类型为'System.Collections.Generic.List'1 [WindowsFormsApp1.TestedParameter]的对象”   不能转换为类型'System.Collections.Generic.List`1 [WindowsFormsApp1.TestedParameter]'。”

我也尝试在没有ToArray（）的情况下推送parametersArrayx，但是它也没有起作用

任何人都可以看一下代码，让我知道我做错了什么吗？ 我想从DLL lib执行带有推送参数列表的代码（后来我想从XML文件导入这些参数。）

谢谢：）

Answer 1

SearchedType.GetMethod("Measure1"); 

转换为

   SearchedType.GetMethod("Measure1", new Type[] { typeof(List<Filter>) });
