For the forced conversion and try conversion methods of C,

Convert the Object type of the String [] type to the String [] type:

1 public string ObjectToString (object ob) 2 {3 string str = string. empty; 4 if (ob is string []) 5 {6 string [] strList = (string []) ob;
7} 8 9 return str; 10}

Use is to determine whether ob is of the string [] type.

Convert string type to DateTime type:

1 public DateTime StringToDateTime (string str) 2 {3 DateTime dateTime = new DateTime (); 4 if (DateTime. tryParse (str, out dateTime) 5 {6 return dateTime; 7} 8 return dateTime; 9}

Note:

When DateTime. TryParse (); is used for conversion judgment, if true is returned, the forced conversion result will be passed into DateTime; if false is returned, the forced conversion cannot be performed.

You can also use Convert. ToDateTime (); to forcibly Convert the data, but you cannot determine whether the data can be forcibly converted. If the data cannot be forcibly converted, an exception is thrown.
