Method for assigning asp.net Crystal Report parameter fields to code

An example of how the asp.net Crystal Report parameter field is assigned to the code is given.Share it for your reference.The implementation is as follows:

//  Declares the variables required to pass parameters to the viewer control. 
ParameterFields paramFields = new ParameterFields (); 
ParameterField paramField = new ParameterField (); 
ParameterDiscreteValue discreteVal = new ParameterDiscreteValue (); 
ParameterRangeValue rangeVal = new ParameterRangeValue (); 
//  No. 1 Parameters are discrete parameters with multiple values.Set the name of the parameter field, which must match the parameters in the report.  
paramField.ParameterFieldName = " Customer Name "; 
//  Settings 1 And pass it to the parameter.  
discreteVal.Value = "AIC Childrens"; 
paramField.CurrentValues.Add (discreteVal); 
//  Settings 2 And pass it to the parameter. discreteVal  The variable is set to a new value so that previous settings are not overwritten.  
discreteVal = new ParameterDiscreteValue (); 
discreteVal.Value = "Aruba Sport"; 
paramField.CurrentValues.Add (discreteVal); 
//  Add this parameter to the parameter field collection.  
paramFields.Add (paramField); 
//  No. 2 Parameters are area values. paramField  The variable is set to a new value so that previous settings are not overwritten.  
paramField = new ParameterField (); 
//  Set the name of the parameter field, which must match the parameters in the report.  
paramField.ParameterFieldName = " Customer  ID"; 
//  Sets the start and end values of the range and passes the range to the parameter.  
rangeVal.StartValue = 42; 
rangeVal.EndValue = 72; 
paramField.CurrentValues.Add (rangeVal); 
//  Will 2 Parameters are added to the parameter field collection.  
paramFields.Add (paramField); 
//  Put the parameter field collection into the viewer control.  
crystalReportViewer1.ParameterFieldInfo = paramFields;

Here are my own applications:

public void OnePage(CrystalReportViewer crystalReportViewer,int a)
{
 ParameterFields paramFields = new ParameterFields();
 ParameterField paramField = new ParameterField();
 ParameterDiscreteValue discreteVal = new ParameterDiscreteValue();
 //  No. 1 Parameters are discrete parameters with multiple values.Set the name of the parameter field, which must match the parameters in the report.  
 paramField.ParameterFieldName = "ARC_I_ID";
 //  Sets the discrete value and passes it to the parameter. 
 discreteVal.Value = id;
 paramField.CurrentValues.Add(discreteVal);
 //  Add this parameter to the parameter field collection. 
 paramFields.Add(paramField);
 //  Put the parameter field collection into the viewer control.  
 crystalReportViewer.ParameterFieldInfo = paramFields;
}

The first code has two parameter fields, and the second code has one.

I hope that the description in this paper will be helpful to everyone's asp.net program design.
