问题 I'm trying to get the contents of a Text File, delete a line of string, and re-write back to the Text File, deleting the line of string. I'm using StreamReader to get the text, importing into a List, removing the string, then rewriting using StreamWriter. My problems arises somewhere around the removing or writing of the string. Instead of writing back the existing, non deleted contents to the text file, all the text is replaced with : System.Collections.Generic.List`1[System.String] My code

问题 Im working with a sparse matrix and im given a text file like this: 0 3 1.2 2 5 3.2 3 0 2.1 3 5 4.2 4 5 2.2 0 0 5.2 Basically the way it works is the number 1.2 goes on the position [0] [3] and the elements of the matriz that are not mentioned stay at 0, so in this case it should look like this: 5.2 0 0 1.2 0 0 0 0 0 0 0 0 0 0 0 0 0 3.2 2.1 0 0 0 0 4.2 0 0 0 0 0 2.2 回答1: OP wrote this in the comments: Im so sorry but my teacher clarified everything just now... it turns out that, for each line

I feel like I've done this correctly, but I can't test it. I can not figure out how to reference this.Controls.Add(chk[I]); to the winForm I want to call it on. The error I get is about it being illegal in a
