The following table shows the default values of value types returned by the default constructors. Default constructors are invoked by using the new operator, as follows:
int myInt = new int();
The preceding statement has the same effect as the following statement:
int myInt = 0;
Remember that using uninitialized variables in C# is not allowed.
| Value type | Default value |
|---|---|
| bool | false |
| byte | 0 |
| char | '\0' |
| decimal | 0.0M |
| double | 0.0D |
| enum | The value produced by the expression (E)0, where E is the enum identifier. |
| float | 0.0F |
| int | 0 |
| long | 0L |
| sbyte | 0 |
| short | 0 |
| struct | The value produced by setting all value-type fields to their default values and all reference-type fields to null. |
| uint | 0 |
| ulong | 0 |
| ushort | 0 |
