On the front properties page of the variable script, amend the ReadOnlyVariables (or ReadWriteVariables) property and select the variables you are interested in. This will enable the selected variables within the script task
Within code you will now have access to read the variable as

string myString = Variables.MyVariableName.ToString();

Accessing package variables in a Script Component  of a Data Flow Task  is not the same as accessing package variables in a Script Task  For a Script Component  you first need to open the Script Transformation Editor  right-click on the component and select  Edit       In the Custom Properties section of the Script tab  you can enter  or select  the properties you want to make available to the script  either on a read-only or read-write basis   Then  within the script itself  the variables will be available as strongly-typed properties of the Variables object      Modify as necessary public override void PreExecute         base PreExecute        string thePath   Variables FilePath         Do something        public override void PostExecute         base PostExecute        string theNewValue              Do something to figure out the new value        Variables FilePath   theNewValue     public override void Input0 ProcessInputRow Input0Buffer Row        string thePath   Variables FilePath         Do whatever needs doing here         One important caveat  if you need to write to a package variable  you can only do so in the PostExecute   method   Regarding the code snippet   IDTSVariables100 varCollection   null  this VariableDispenser LockForRead  User  FilePath    string XlsFile   XlsFile   varCollection  User  FilePath   Value ToString      varCollection is initialized to null and never set to a valid value  Thus  any attempt to dereference it will fail

I had the same problem as the OP except I remembered to declare the ReadOnlyVariables    After some playing around  I discovered it was the name of my variable that was the issue   File Path  in SSIS somehow got converted to  FilePath   C  does not play nicely with underscores in variable names   So to access the variable  I type  string fp   Variables FilePath    In the PreExecute   method of the Script Component

This should work    IDTSVariables100 vars   null  VariableDispenser LockForRead  System  TaskName    VariableDispenser GetVariables vars   string TaskName   vars  System  TaskName   Value ToString    vars Unlock      Your initial code lacks call of the GetVariables   method

First List the Variable that you want to use them in Script task at ReadOnlyVariables in the Script task editor and Edit the Script  To use your ReadOnlyVariables in script code   String codeVariable   Dts Variables  User  VariableNameinSSIS   Value ToString      this line of code will treat the ssis package variable as a string
