在我的一个项目中，我使用MS SRS并解决了此问题，如下所示:

In one of my projects I used MS SRS and solved this issue as shown below:

<br />
using System;<br />
using System.Collections.Generic;<br />
using System.Linq;<br />
using System.Web;<br />
using Microsoft.Reporting.WebForms;<br />
<br />

{<br />
    public class ReportParametersBLL<br />
    {<br />
        public string ReportName { get; set; }<br />
        public List<ReportParameter> Parameters { get; set; }<br />
<br />
        public ReportParametersBLL()<br />
        {<br />
            Parameters = new List<ReportParameter>();<br />
        }<br />
<br />
        private void AddParameter(ReportParameter reportParameter)<br />
        {<br />
            if (reportParameter != null)<br />
            {<br />
                Parameters.Add(reportParameter);<br />
            }<br />
        }<br />
<br />
        public void AddParameter(string parameterName, string parameterValue)<br />
        {<br />
            if (!string.IsNullOrEmpty(parameterName))<br />
            {<br />
                ReportParameter reportParameter = new ReportParameter(parameterName, parameterValue);<br />
                AddParameter(reportParameter);<br />
            }<br />
        }<br />
<br />
        public void AddParameterWithNullValue(string parameterName)<br />
        {<br />
            if (!string.IsNullOrEmpty(parameterName))<br />
            {<br />
                ReportParameter reportParameter = new ReportParameter(parameterName);<br />
                reportParameter.Values[0] = null;<br />
                AddParameter(reportParameter);<br />
            }<br />
        }<br />
<br />
        public void AddParameter(string parameterName, List<string> parameterValues)<br />
        {<br />
            if (!string.IsNullOrEmpty(parameterName)&&parameterValues.Count>0)<br />
            {<br />
                ReportParameter reportParameter = new ReportParameter(parameterName);<br />
                foreach (var parameterValue in parameterValues)<br />
                    reportParameter.Values.Add(parameterValue);<br />
                AddParameter(reportParameter);<br />
            }<br />
        }<br />
<br />
        public void AddParameter(string parameterName, List<int> parameterValues)<br />
        {<br />
            if (!string.IsNullOrEmpty(parameterName) && parameterValues.Count > 0)<br />
            {<br />
                ReportParameter reportParameter = new ReportParameter(parameterName);<br />
                foreach (var parameterValue in parameterValues)<br />
                    reportParameter.Values.Add(parameterValue.ToString());<br />
                AddParameter(reportParameter);<br />
            }<br />
        }<br />
<br />
        public void ClearReportParameters()<br />
        {<br />
            Parameters = new List<ReportParameter>();<br />
        }<br />
    }<br />
}<br />
