Implementing methods for casting and attempting transformations in C #

This article is mainly for you to introduce in detail the C # cast and try to convert the method, with a certain reference value, interested in small partners can refer to

The example of this article for you to share the C # cast and try to convert the method for your reference, the specific content is as follows

Convert an object type of string[] type to a string[] type:

public string Objecttostring (object ob) {  string str = string. Empty;  if (ob is string[])  {    string[] strlist = (string[]) ob;   }  return str;}

Use is to determine if OB is string[] type.

To convert a string type to a DateTime type:

public datetime stringtodatetime (String str) {  datetime datetime = new DateTime ();  if (Datetime.tryparse (str, out datetime))  {    return datetime;  }  return dateTime;}

Attention:

Use Datetime.tryparse (); When the conversion is judged, if true, the cast result is passed into DateTime, and if False is returned, it cannot be cast.

You can also use Convert.todatetime (); Cast, but it is not possible to determine whether a cast can be made, and an exception is reported when the conversion cannot be cast.
