Passing Multiple parameter values to Crystal Report using Stored Procedure

I am using Visual Studio 2012 , Window Form Application . I have created a report with Crystal report using stored procedure which accepts three parameters i-e @DateFrom, @DateTo, and @District, i have to pass these parameters from c# code.

I have the following code which accepts only one parameter not multiple, please help me 

private void btn_Preview_Click(object sender, EventArgs e)
{
                string parm_From = "01-07-2014";
                string param_To = "30-06-2015";
                string param_District = "DistrictName";
                ReportDocument reportDocument = new ReportDocument();
                ParameterField paramField = new ParameterField();
                ParameterFields paramFields = new ParameterFields();
                ParameterDiscreteValue paramDiscreteValue = new ParameterDiscreteValue();

                paramField.CurrentValues.Add(parm_From);
                paramFields.Add(paramField);
                crystalReportViewer1.ParameterFieldInfo = paramFields;
                reportDocument.Load(@"\GenPensionReport.rpt");
                crystalReportViewer1.ReportSource = reportDocument;
                crystalReportViewer1.Refresh(); 
}

where i am going wrong?

        CrystalReport1 objRpt = new CrystalReport1();
        objRpt.SetDataSource(ds);
        ParameterFields pfield = new ParameterFields();
        ParameterField ptitle = new ParameterField();
        ParameterField ptitle1 = new ParameterField();
        ParameterField ptitle2 = new ParameterField();
        ParameterDiscreteValue pvalue;
        ParameterDiscreteValue pvalue1;
        ParameterDiscreteValue pvalue2;
        ptitle.ParameterFieldName = "pdate";//pdate is a crystal report parameter name
        ptitle.CurrentValues.Clear();
        pvalue = new ParameterDiscreteValue();
        ptitle.CurrentValues.Add(pvalue);
        pvalue.Value = txtcolor.Text.ToString();

        pfield.Add(ptitle);

        ptitle1.ParameterFieldName = "no";//no is a crystal report parameter name
        ptitle1.CurrentValues.Clear();
        pvalue1 = new ParameterDiscreteValue();
        ptitle1.CurrentValues.Add(pvalue1);
        pvalue1.Value=txtno.Text.ToString();

        pfield.Add(ptitle1);

        ptitle2.ParameterFieldName = "date";//date is a crystal report       parameter name
        ptitle2.CurrentValues.Clear();
        pvalue2 = new ParameterDiscreteValue();
        ptitle2.CurrentValues.Add(pvalue2);
        pvalue2.Value = textBox1.Text.ToString();

        pfield.Add(ptitle2);

        crystalReportViewer1.ParameterFieldInfo = pfield;

After you load the report document, you just need to call:

reportDocument.SetParameterValue("DateFrom", dateFrom);
reportDocument.SetParameterValue("DateTo", dateTo);
reportDocument.SetParameterValue("District", district);

EDIT

// The names must match what Crystal expects, So if they contain @ you must include them.
reportDocument.SetParameterValue("@DateFrom", dateFrom);
reportDocument.SetParameterValue("@DateTo", dateTo);
reportDocument.SetParameterValue("@District", district);

This simply sets the parameter values to the report.
