推荐答案

使用此值将值传递给水晶报表中的参数

Use this to pass value to your parameter in crystal report

Using CrystalDecisions.Shared; //add this namespace;


ParameterFields paramfields = new ParameterFields(); //collection of parameters
ParameterField paramfield = new ParameterField(); //your parameter
ParameterDiscreteValue dsvalue = new ParameterDiscretValue(); // holder of your the value for the parameter


paramfield.Name = "Nameofparameter in crystal report"
dsvalue.Value = "the value you want to pass";
paramfield.CurrentValue.Add(dsvalue); //this assign the value to your parameter
paramfields.Add(paramfield); //add the parameterfield to the parameterfields collection

crystalReportViewer1.ParameterFieldInfo = paramfields; //this will assign the parameter fields to the report loaded in crystalreportviewer1

loadordinfo(); // call this method here

你也可以试试这个1.

hope it helps.

you can also try this 1.

private void OrdersBillReport_Load(object sender, EventArgs e)
{
    conn = new MySqlConnection(path.p);
    CargoPrivateFontCollection();
    CargoEtiqueta(font);

    oo = new orgnization();
    oo.orgnizationinfo();

    crystalReportViewer1.ReuseParameterValuesOnRefresh = false;
    objRpt.SetParameterValue("n", oo.organame.ToString());

    loadordinfo();

}
