索引超出范围。 在处理本地报告期间，必须为非负数并且小于集合的大小

Question

我得到以下异常

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

调用此方法时：

private void AddReportToResponse(LocalReport Report)
{
    string mimeType;
    string encoding;
    string extension;
    string[] streams = new string[100];
    Warning[] warnings = new Warning[100];
    byte[] pdfStream = Report.Render("PDF", "", out mimeType, out encoding, out extension, out streams, out warnings);//The error here
    Response.Clear();
    Response.ContentType = mimeType;
    Response.AddHeader("content-disposition", "attachment; filename=Application." + extension);
    Response.BinaryWrite(pdfStream);
    Response.End();
}

经过大量的搜索和调试，我发现了问题的原因：

我在报表中使用了matrix ，而且渲染可能不正确，因此我只是尝试将此矩阵的数据源设置为空数据表，并且工作正常。 所以我知道问题出在哪里，经过一些（调整）矩阵的高度和宽度后，所有事情都可以了：
