The name 'temp' does not exist in the current context (C# desktop application)

问题

I am making a C# desktop application with following code:

static class ClassA
{
     public static string Process()
     {
          string temp = Functions.Test();
          return temp;
     }
}

static class Functions
{
     public static string Test()
     {
          return "ok";
     }
}

Problem is the variable "temp" doesn't get any value from Test() funciton. When I try to check its value in Immediate Window, I get the message "The name 'temp' does not exist in the current context"

Both ClassA and Functions are in separate class files but belong to same namespace.

回答1:

try with

static class ClassA
{
 string temp = Functions.Test();
 public static string Process()
 {
      return temp;
 }
}

static class Functions
{
 public static string Test()
 {
      return "ok";
 }
}

I know this is an older question, but hopefully this will help newer developers as well: I came across a similar issue and realized that my two classes (which are in two different projects) were targeting two different frameworks. Once I switched them to both target Net Framework 4.5 they compiled perfectly and without this issue.

The only way I can reproduce the error is by checking

? temp

in the Immediate Window when the code is not running.

If you call the actual method by

? ClassA.Process()

it works just fine.

Also, if you place a breakpoint on the return temp; line and run your program, the Immediate Window will give the correct result when checking

? temp

when the debugger stops at you breakpoint. At this point temp will be in the current context.

Adding the following to your code:

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine(ClassA.Process());
        Console.ReadLine();
    }
}

returns "ok"

Something else is wrong with your code.
