你好
Iftikar H ,
通常,有几个原因导致您收到此错误:
Usually, There are several reasons why you might be receiving this error:
1.您可能拼写错误了您尝试使用的类型或命名空间的名称。如果没有正确的名称,编译器将无法找到您在代码中引用的类型或命名空间的定义。这通常是因为
C#是区分大小写,并且在引用类型时没有使用正确的大小写。
1. You might have misspelled the name of the type or namespace that you are trying to use. Without the correct name, the compiler is unable to find the definition for the type or namespace that you referred to in your code. This occurs most often because C# is case-sensitive and you did not use the correct capitalization when you referred to the type.
2.如果错误是对命名空间的引用,则可能没有在项目中引用命名空间的程序集。
2. If the error is a reference to a namespace, you may not have the assembly where the namespace is located referenced in your project.
3.如果错误是对类型的引用,那么您可能没有正确使用directiv e,或者您可能没有完全限定类型的名称。
3. If the error is a reference to a type, then you may not have the proper using directive, or you may have not fully qualified the name of the type.
解决方法:
当您收到此编译器错误时,首先要做的事情是检查是拼写。如前所述,最常见的原因是没有类型或命名空间的正确情况。如果您确定已正确拼写了类型或命名空间的名称
(包括正确的大小写),请检查以下内容:
When you receive this compiler error, the first thing to check is spelling. As previously noted, the most common cause is not having the correct case for the type or namespace. If you feel certain that you have spelled the name of the type or namespace correctly (including the correct capitalization), then check the following:
