获取Dynamic CRM选项集类型（OptionSet）字段的文本（label）值

前端（Js）

Xrm.Page.getAttribute(fieldname).getText();
Xrm.Page.getAttribute(fieldname).getValue();

后端（C#）

 public static string GetOptionsSetTextOnValue(IOrganizationService service, string entityName, string attributeName, int selectedValue)
    {

        RetrieveAttributeRequest retrieveAttributeRequest = new RetrieveAttributeRequest
        {
            EntityLogicalName = entityName,
            LogicalName = attributeName,
            RetrieveAsIfPublished = true
        };

        RetrieveAttributeResponse retrieveAttributeResponse = (RetrieveAttributeResponse)service.Execute(retrieveAttributeRequest);

        Microsoft.Xrm.Sdk.Metadata.PicklistAttributeMetadata retrievedPicklistAttributeMetadata = (Microsoft.Xrm.Sdk.Metadata.PicklistAttributeMetadata)

        retrieveAttributeResponse.AttributeMetadata;
        OptionMetadata[] optionList = retrievedPicklistAttributeMetadata.OptionSet.Options.ToArray();
        string selectedOptionLabel = string.Empty;
        foreach (OptionMetadata oMD in optionList)
        {
            if (oMD.Value == selectedValue)
            {
                selectedOptionLabel = oMD.Label.UserLocalizedLabel.Label;
            }
        }
        return selectedOptionLabel;
    }

正常情况下我们获取到的都是Value值，通过上述代码就可以获取到Value对应的Label值。
