Example 1 uses int. Parse method to realize the transformation, which usually needs to catch and handle the exceptions that appear during the transformation.
String? s？ =? ……;
int？ The result? =? 0;
attempt
{
The result? =? The analysis inside;
Console. WriteLine ("The converted integer value is: {0}",? Results);
}
catch
{
Console. WriteLine ("Cannot complete conversion!" );
} Example 2 uses int. The TryParse method is used to realize the conversion, and there is no need to handle the exceptions that occur during the conversion.
String? s？ =? ……;
int？ Results;
if(int。 Trypsin (s, out? Results))
{
Console. WriteLine ("The converted integer value is: {0}",? Results);
}
other
{
Console. WriteLine ("Cannot complete conversion!" );
} it is recommended to use int. TryParse method!
