从DSO迁移到AMO时，无法检索Command（AMO中的MdxScripts）的自定义属性

Question

我正在从DSO迁移到AMO以获取SSAS。以下是我们如何创建Command并添加自定义属性的小样本，以后我们可以使用DSO进行检索。这是C ++中的当前DSO实现。

        CString sWAMeasureName = sMeasureName;
        CString sStatement = "Create Member CURRENTCUBE.[Measures].[" + sWAMeasureName + "] as \' " + sExpression + "\', FORMAT_STRING = \'" + sFormat + "\', VISIBLE = 1";

        if (pCube->Commands->Find((const char*)sWAMeasureName))
        {
            pCube->Commands->Remove((const char*)sWAMeasureName);
            pCube->Update();
        }

        _CubeCommandPtr cubeCommand = pCube->Commands->AddNew((const char*)sWAMeasureName, sbclsRegular);
        cubeCommand->CommandType = cmdCreateMember;
        cubeCommand->Statement = (const char*)sStatement;
        cubeCommand->CustomProperties->Add((const char*)sAggrFunction, "AggrFunc", (VbVarType)8 /*vbString*/);
        cubeCommand->CustomProperties->Add((const char*)sAggrArg, "AggrArg", (VbVarType)8 /*vbString*/);
        cubeCommand->CustomProperties->Add((const char*)sSourceColumn, "SourceColumn", (VbVarType)8 /*vbString*/);
        cubeCommand->CustomProperties->Add((const char*)sNumMeasureName, "NumMeasName", (VbVarType)8 /*vbString*/);
        cubeCommand->CustomProperties->Add((const char*)sDenMeasureName, "DenMeasName", (VbVarType)8 /*vbString*/);
        pCube->Update();

在我们迁移到AMO之后，我需要能够从AMO中的命令（AMO中的mdxscript）对象中检索自定义属性。到目前为止我无法得到它们。我在这做错了什么？这是我在C＃中编写的示例代码。

var list = new List<String>();
var cube = GetCubeByName(catalog, sCube);

for (int i = 0; i < cube.MdxScripts.Count; i++)
{
    for (int m = 0; m < cube.MdxScripts.Count; m++)
        for (int c = 0; c < cube.MdxScripts[i].Commands.Count; c++)
        {
            foreach (Annotation ann in cube.MdxScripts[i].Annotations)
            {
                //Doesn't get here
            }

            foreach (CalculationProperty ann in cube.MdxScripts[i].CalculationProperties)
            {
                //Doesn't get here
            }
        }
}
