Per click a button to invoke a getTextList, such as good 5 seconds then click, when click a third time:
The catch (Exception ex)
{
Console. WriteLine (" [ERROR] "+ ex. Message. The ToString ());
}
The exception is caught,

CodePudding user response:

Are you sure the while (STR!=string. The Empty) is not an infinite loop? Generally the sr. ReadLine () no, value is null, you can use the while (! String. IsNullOrEmpty (STR)) have a try,

CodePudding user response:

Only read the words, a file opened in read-only mode

FileStream stream=new FileStream (" path ", FileMode. Open, FileAccess. Read, FileShare. Read);

CodePudding user response:

Why bother?
String [] a=File. ReadAllLines (FileName);
Or;
Var list=File. ReadAllLines (FileName) ToList ();


How simple!
