Console.Write Method (Object)

Writes the text representation of the specified object to the standard output stream.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

[HostProtectionAttribute(SecurityAction.LinkDemand, UI = true)]
public static void Write(
	Object value
)

Parameters

value
Type: System.Object

The value to write, or null.

ExceptionCondition
IOException

An I/O error occurred.

If value is null, nothing is written and no exception is thrown. Otherwise, the ToString method of value is called to produce its string representation, and the resulting string is written to the standard output stream.

NoteNote

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: UI. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

The following example illustrates the use of the Write method.

public class FormatConverter {
    public static void Main(string[] args) {
        string lineInput;
        while ((lineInput = Console.ReadLine()) != null) {
            string[] fields = lineInput.Split(new char[] {'\t'});
            bool isFirstField = true;
            foreach(string item in fields) {
                if (isFirstField)
                    isFirstField = false;
                else
                    Console.Write(',');
                // If the field represents a boolean, replace with a numeric representation. 
                try {
                    Console.Write(Convert.ToByte(Convert.ToBoolean(item)));
                }
                catch(FormatException) {
                    Console.Write(item);
                }
            }
            Console.WriteLine();
        }
    }
}
