使用Google设置MetricAggregations

Question

我在C#中编写代码，并使用Google.Analytics.Data.V1Beta库检索GA4数据。

我想发送到api的查询如下：

{
"dimensions": [
    {
        "name": "pageLocation"
    }
],
"metrics": [
    {
        "name": "screenPageViews"
    }
],
"dateRanges": [
    {
        "startDate": "2022-01-01",
        "endDate": "2022-07-19"
    }
],
"dimensionFilter": {
    "filter": {
        "stringFilter": {
            "matchType": "PARTIAL_REGEXP",
            "value": "l-\\d{6,}"
        },
        "fieldName": "pageLocation"
    }
},
"limit": "1",
"metricAggregations": [
    "TOTAL"
]}

查询的重要部分是metricAggregations属性。这是我的密码

var request = new RunReportRequest
  {
    Property = "properties/" + myPropertyId,
    Dimensions = {
      new Dimension { Name = "pageLocation" }
    },
    DimensionFilter = new FilterExpression
    {
      Filter = new Filter
      {
        StringFilter = new Filter.Types.StringFilter { 
          CaseSensitive = true, 
          MatchType = Filter.Types.StringFilter.Types.MatchType.PartialRegexp, 
          Value = @"l-\d{6,}" 
        },
        FieldName = "pageLocation"
      }
    },
    Metrics = {
      new Metric { Name = "screenPageViews" }
    },
    MetricAggregations=new Google.Protobuf.Collections.RepeatedField<MetricAggregation> { MetricAggregation.Total},
    DateRanges = {
      new DateRange {
        StartDate = "2022-01-01",
        EndDate = "2022-07-19"
      }
    },
  };

  // Make the request
  var response = await _client.RunReportAsync(request);

问题是，MetricAggregations属性是只读属性，因此会引发错误。

显示的错误是“度量的聚合。聚集的度量值将显示在将dimensionValues设置为"RESERVED_(MetricAggregation)”的行中。

有人能告诉我如何用c#库来设置这个参数吗？

问候

希望我找到了答案。

要填充MetricAggregations属性，一旦创建了请求对象，只需调用该属性的Add方法即可。

就我而言：

request.MetricAggregations.Add(MetricAggregation.Total );
