报告查看器问题
我正在使用报告查看器生成报告。以下是我正在使用的代码
ReportViewer1.LocalReport.ReportPath = @"C:\Users\Saga\Desktop\projectvn\VehicleReport.rdlc";
ReportParameter Param1 = new ReportParameter("@BrandName", "Toyota");
ReportParameter[] p1 = { Param1 };
ReportViewer1.LocalReport.SetParameters(p1);
它给出了以下异常
An error occurred during local report processing
有人可以帮忙吗？

确保您已在报告中添加参数（“菜单报告”>“报告参数”），如果您已完成此操作，请确保未将其标记为内部，否则该参数为只读。
Make sure you've added the parameter in the report (Menu Report > Report Parameters) and if you have done that already, make sure that is not marked as internal otherwise the parameter is read-only.
当然，在我看来，参数“@BrandName”指定不正确...您可以在实际报告文件中仔细检查其名称吗？也许它有不同的大写（例如“@Brandname”）或间距（“@Brand_Name”）或没有 at 符号（“BrandName”）。,,
Sure looks to me like the parameter '@BrandName' is specified incorrectly... can you double-check its name in the actual report file? Perhaps it has different capitalization (e.g. "@Brandname") or spacing ("@Brand_Name") or no at-sign ("BrandName").,,
看起来绝对是报告方。确保你有一个名为 @BrandName 的参数，并且无论控件是什么，确保它的使用方式如下：
这只是标准的，还有其他方法用于不同的事物，例如字段等
Definatly looks to be the report side. Make sure you have a paramter called @BrandName and that what ever the control is, make sure its using it something like:
This is just standard there are other methods for different things like fields etc
