Example:
nome = "Josénildo da Silva Ramos do Carmo";
Cut to have up to X characters, thus:
nome = "Josénildo da Silva ";
In the case I cut it to 20 characters.
How do I do this in C #? I only know in C (which is vector). In C # I could not find how.
It's quite simple:
nome = nome.Substring(0, 20);
In this case you are picking up 20 characters from the character at position 0.
Method documentation . From here you can see in the documentation all methods that type String allows. It is good to give a decoration in everything to know what already exists.
See running on dotNetFiddle .
Use the Substring method.
var nome = "Josénildo da Silva Ramos do Carmo";
var novoNome = nome.Substring(0, 20);
The first parameter indicates the initial index and the second is the character count that must be cut, ie the above method will pick up from position 0 to 20 of the string.
