C# Regex quick help -

-

I am trying to read a text file, and then breaks it from each line that is "\ n". Then do it again and type regedix. 

  string content = file. Read all the text (filename); String [] firefox = file name. Sample ("\ r \ n"); String prefix = prefix = regesx. Match (Firefox, @ "(\ d)"). Group [0]. value; File. Application all text (working format 2 + "configuration.txt", prefix);

string [] Firefox = file name. Sample ("\ r \ n"); Does not work at all

What I want to do, runs the regex front line of content and then write each line after regex

so ...

< P> filename:
Hero 123
Hero 243
Hero 5959

writes this:



595 5959

OK , Everybody is suggesting some of the bases in which I started the regex with a 20-line Inge about the end result. I've got to parse it out of the line. 

  var rows = file. Read Line (Basic Path); File. Select All Lines Merge (Newpath, Lines. (L = & gt; Reggae. Match (l, @ "\ d +"). Value) .Oir ());

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
