The string reference variable is assigned to the null literal. Next, the Length property is accessed on the string reference. The program compiles correctly, but will always throw an execution.Note:You cannot access an instance property like Length on a null reference. An exception will always occur.You need to debug your program and check for all possible null values.[Update]Check ent and Repeater1 object for null values before using it.   --Amy 这篇关于在本地服务器中，该文件未显示任何错误，但在Web服务器上显示此错误的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
