问题 I get an error indicating that MyRandomArray doesn't exist in the current context. How do you access variables across classes in a C# WinForms application? public void Quiz_Load(object sender, EventArgs e) { string[] MyRandomArray = getWordList(); } private void timer1_Tick(object sender, EventArgs e) { somefunction(MyRandomArray);/// MyRandomArray doesn't exist in the current context. } 回答1: You've defined the array, but only in the scope of the Quiz_Load method, so the scope of timer1_Tick

问题 I’m writing a program that pulls a list of departments from a database. I want to avoid hardcoding this since the list may change. I want to create a variable for each department to populate questions into a GUI. The problem I have is that I can create variables from the database list using the vars() function. I’m then storing the list of variable names so I can reference them elsewhere in my program. As long as I do everything in the same def, there is no problem. But I don’t know how to

问题 I am trying to run a shell script from python by exporting the python variable to the shell script instead of directly reading them from the user. A question regarding passing array values as variable to shell script was answered successfully earlier and helped me to pass the values in an array as a input variable to the shell script. I want to export multiple variables such as FLUID , TTYPE and FLIBRARY from the following python script: FLUID="MDM" TTYPE=0 FLIBRARY="RefProp" HSPACE=[0.01, 0

问题 In bash, if I run (foo=14) And then try to reference that variable later on in my bash script: echo "${foo}" I don't get anything. How can I make bash store this variable the way I need it to? Specifically, I am using this in an if statement and checking the exit code, something kind of like: if (bar="$(foo=14;echo "${foo}"|tr '1' 'a' 2>&1)") then echo "Setting "'$bar'" was a success. It is ${bar}" else echo "Setting "'$bar'" failed with a nonzero exit code." fi 回答1: Commands enclosed in

问题 I already have a working, but in my oppinion not beautiful solution for a part of a long script. My script uses several similar methods, that differ too much to combine. However I came to a point where I want to call one of those methods depending on a given variable. The names of the methods are build up like this: def read_A(): #doing sth def read_B(): #doing sth else def read_C(): etc. Now I would like to call those methods in a pythonic way, when the letter ( 'A' , 'B' , 'C' , ...) is

问题 I was recently given the advice to export variables from a batch script to a text file using set $>savefile and returning said variables upon another startup using for /f "delims=" %%a in (savefile) do set %%a In implementation, this is not creating a file with the variables, resulting in error in the script, which closes the batch. To remedy the closing, I created a check to display an error message, but still cannot get the script to export variables into a file. Variables ::Variables set

问题 I want to ask you how to declare a variable that can be used by every method? I tried making the method's access type public but that didn't let me used its variable across other methods Moreover, I basically want to accumulate that variable with different values across different methods that's why I am asking this. NOTE: I want to avoid making any static classes. EDIT: For example, I did public decimal MiscMethod() { decimal value1 += 23m; } public decimal AutoMethod() { decimal value 1 +=
