How do I truncate a .NET string?
- by Steve Guidi
I apologize for such a question that likely has a trivial solution, but I strangely could not find a concise API for this problem.
Essentially, I would like to truncate a string such that it its length is not longer than a given value. I am writing to a database table and want to ensure that the values I write meet the constraint of the column's datatype.
For instance, it would be nice if I could write the following:
string NormalizeLength(string value, int maxLength)
{
return value.Substring(0, maxLength);
}
Unfortunately, this raises an exception because maxLength exceeds the string boundaries. Of course, I could write a function like the following, but I was hoping that something like this already exists.
string NormalizeLength(string value, int maxLength)
{
return value.Length <= maxLength ? value : value.Substring(0, maxLength);
}
Where is the elusive API that performs this task? Is there one?
