示例1: Main
//引入命名空间
using System;
public class Example
{
public static void Main()
{
try {
// Outer block to handle any unexpected exceptions.
try {
string s = "This";
s = s.Insert(2, "is ");
// Throw an OutOfMemoryException exception.
throw new OutOfMemoryException();
}
catch (ArgumentException) {
Console.WriteLine("ArgumentException in String.Insert");
}
// Execute program logic.
}
catch (OutOfMemoryException e) {
Console.WriteLine("Terminating application unexpectedly...");
Environment.FailFast(String.Format("Out of Memory: {0}",
e.Message));
}
}
}输出：
Terminating application unexpectedly...
示例2: Main
//引入命名空间
using System;
using System.Text;
public class Example
{
public static void Main()
{
StringBuilder sb = new StringBuilder(15, 15);
sb.Append("Substring #1 ");
try {
sb.Insert(0, "Substring #2 ", 1);
}
catch (OutOfMemoryException e) {
Console.WriteLine("Out of Memory: {0}", e.Message);
}
}

示例3: Main
//引入命名空间
using System;
using System.Collections.Generic;

}
private static Double GetMean(Double[] values)
{
Double sum = 0;
foreach (var value in values)
sum += value;
return sum / values.Length;
}
}输出：
