Question

我有以下代码。我们争论哪种方法更适合内存性能。如果我们不使用单独的变量并使用它，它会有什么不同吗？它会影响那么这是可能的解决方案吗？

    /// <summary>
    /// Treatment Point Types
    /// </summary>
    public string DWTreatment
    {
        get
        {
            StringBuilder sbStatus = new StringBuilder();
            .........

        }

        set
        {
            chkTreatSR.Checked = value.Split(',').Contains(((int)AgencyListReportTemplate.SamplingPointTypesEnum.SR).ToString());
            chkTreatIT.Checked = value.Split(',').Contains(((int)AgencyListReportTemplate.SamplingPointTypesEnum.IT).ToString());
            chkTreatEP.Checked = value.Split(',').Contains(((int)AgencyListReportTemplate.SamplingPointTypesEnum.EP).ToString());
            chkTreatWW.Checked = value.Split(',').Contains(((int)AgencyListReportTemplate.SamplingPointTypesEnum.WW).ToString());
            chkTreatQC.Checked = value.Split(',').Contains(((int)AgencyListReportTemplate.SamplingPointTypesEnum.QC).ToString());

            isSelectionSetByPage = true;
        }
    }

OR

    /// <summary>
    /// Treatment Point Types
    /// </summary>
    public string DWTreatment
    {
        get
        {
            StringBuilder sbStatus = new StringBuilder();
            .........

        }

        set
        {
            var values = value.Split(',');
            chkTreatSR.Checked = values.Contains(((int)AgencyListReportTemplate.SamplingPointTypesEnum.SR).ToString());
            chkTreatIT.Checked = values.Contains(((int)AgencyListReportTemplate.SamplingPointTypesEnum.IT).ToString());
            chkTreatEP.Checked = values.Contains(((int)AgencyListReportTemplate.SamplingPointTypesEnum.EP).ToString());
            chkTreatWW.Checked = values.Contains(((int)AgencyListReportTemplate.SamplingPointTypesEnum.WW).ToString());
            chkTreatQC.Checked = values.Contains(((int)AgencyListReportTemplate.SamplingPointTypesEnum.QC).ToString());

            isSelectionSetByPage = true;
        }
    }

感谢。

第二个示例将减少内存分配，因为每次调用string.Split（，）都会分配一个新的字符串数组。

如果这是代码中的“热点”，您可能会考虑根本不调用string.Split，而是使用Regex搜索您的枚举。
