C# Substring Alternative - Return rest of line within string after character

Question

I have some code that reads a text file and sets it to a string. Each line of the text file contains separate data parameters that I a trying to extract. Here is an small ex

Answer 1

Assuming the text file is in the format posted and only contains the data parameters, an alternative approach would be to read the contents of the file and project the contents into a dictionary since you already know the parameter names, i.e,. "part", "quantity", etc...

Dictionary param = File
    .ReadLines("path.to.file.txt")
    .Select(x => x.Split('='))
    .ToDictionary(x => x[0], y => y[1]);

The contents can then be accessed by the key name, similar to how you were originally assigning the variables:

string partNum = param["part"];

Or, just use the dictionary as needed without assigning to a local variable.
