如何在Wpf中创建显示图像的报告(RDLC)。用实际例子解释:

这段代码不起作用: 

reportViewer.LocalReport.ReportPath = @"C:'Users'dsingh'Documents'Visual Studio 2012'Projects'ReportViewerWPF'ReportViewerWPF'CustomerReport.rdlc";
reportViewer.LocalReport.EnableExternalImages = true;
string imagePath = @"C:'Users'dsingh'Documents'Visual Studio 2012'Projects'ReportViewerWPF'ReportViewerWPF'Penguins - Copy.jpg";
ReportParameter parameter = new ReportParameter("ImagePath", imagePath);
List<ReportParameter> obj = new List<ReportParameter>();
obj.Add(parameter);
reportViewer.LocalReport.SetParameters(obj);
reportViewer.LocalReport.Refresh();

如何创建显示图像的报告(RDLC)

尝试像这样更改imagePath

string imagePath=@"file:///C:'Users'dsingh'Documents'Visual Studio 2012'Projects'ReportViewerWPF'ReportViewerWPF'Penguins - Copy.jpg"

代替reportViewer.LocalReport.Refresh()使用

reportViewer.RefreshReport();

整个代码是这样的

reportViewer.LocalReport.ReportPath = @"C:'Users'dsingh'Documents'Visual Studio 2012'Projects'ReportViewerWPF'ReportViewerWPF'CustomerReport.rdlc";
reportViewer.LocalReport.EnableExternalImages = true;
string imagePath = @"file:///C:'Users'dsingh'Documents'Visual Studio 2012'Projects'ReportViewerWPF'ReportViewerWPF'Penguins - Copy.jpg";
ReportParameter parameter = new ReportParameter("ImagePath", imagePath);
List<ReportParameter> obj = new List<ReportParameter>();
obj.Add(parameter);
reportViewer.LocalReport.SetParameters(obj);
reportViewer.RefreshReport();

确保您在rdlc中正确定义了Report Parameter。
