NUnit运行测试失败

我的设置

CoreExtensions.Host.InitializeService();
package = new TestPackage(pathToTestDll);
builder = new TestSuiteBuilder();
suite = builder.Build(package);

foreach (NUnitTestMethod t in tests)
{
    try
    {
        var res = t.RunTest();
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.ToString());
    }
}

我将此作为异常堆栈:

在System.Reflection.RuntimeMethodInfo.CheckConsistency(Object target)at System.Reflection.RuntimeMethodInfo.InvokeArgumentsCheck(Object obj,BindingFlags invokeAttr,Binder Binder,Object[]parameters,CultureInfo culture)at System.Reflection.RuntimeMethodInfo.Invoke(Object obj,BindingFlags invokeAttr,Binder Binder,Object[]parameters,CultureInfo culture)at,位于NUnit.Core.Reflect.InvokeMethod(MethodInfo方法,Object fixture,Object[]参数)的System.Reflection.MethodBase.Invoke(Object obj,Object[]参数),位于NUnit.Core.TestMethod.RunTestCase(TestResult TestResult)

nunit.core和nunit.core.interfaces在我的测试包和运行包中是相同的文件
