For help, with c # language to create a TXT text, first to save three text box Numbers in text, such as: 23.22 51.56 91.23
Read out respectively according to the three figures again to the original three text boxes, just into the small white, see a lot of online tutorials, see a lot of bosses example, but do not understand what is going wrong, maybe all the time, please, do me a favor

CodePudding user response:

Such as written in | segmentation, inside is 23.22 51.56, 91.23 | | read out on the Split after segmentation

CodePudding user response:

Your code is unknown, here to write and read the text example
And dynamically create control example
Want to see you is how to save the data, if a data line, so, read into an array, and then loop can be assigned to control,

CodePudding user response:

String [] arr=File. ReadAllLines (" 1. TXT ");
TextBox1. Text=arr [0];
TextBox2. Text=arr [1].
TextBox3. Text=arr [2];

Thank you so much, very serious and responsible to play so much code, thank you very much!
