Crystal report-"the report cannot be found in the resource list. Please re-compile the project and try again"

Problem: "Unable to find the report in the manifest resources. Please build the project, and try again"
Cause:
1. Set the Build Action attribute of the report file to "Embedded Resource" ("Embedded Resource ").
2. the namespace of the report class file is inconsistent with the rpt folder of the report file. You can draw a conclusion through a small test to create a small project and display a report, if you modify the namespace of a report class file, this exception is thrown when you use the report object.

Solution:
1. Same cause
2. You can modify the report file name directly and change it back to its original name. The report file namespace is consistent with the report rpt path.
Thank you very much for your reminder.
