推荐答案
检查晶体位于给定路径的位置.
您可以调试代码,在string RepPach = Application.StartupPath + @"\WindowsFormsApplication2\CrystalReport2.rpt";
上放置一个断点,然后在此处读取文件路径.
检查文件是否在该路径下.
CHeck that the crystal resides at the given path.
You can debug through the code, put a break point onstring RepPach = Application.StartupPath + @"\WindowsFormsApplication2\CrystalReport2.rpt";
, and then read the file path here.
Check if the file exists at that path.
Application.StartupPath = "G:\WindowsFormsApplication2\WindowsFormsApplication2\bin\Debug"
//Crystal in this direction is
"G:\WindowsFormsApplication2\WindowsFormsApplication2"
//RepPach of the break point is NULL
//With this command gives error
string RepPach = Application.StartupPath + @"..\..\CrystalReport2.rpt";
