Overloads¶
- 1.
public static bool TrySetValueToPropertyChain<TValue>(object? target, IEnumerable<Expression> expressionChain, TValue value) - 2.
public static bool TrySetValueToPropertyChain<TValue>(object? target, IEnumerable<Expression> expressionChain, TValue value, bool shouldThrow)
1. Overload¶
Attributes: [RequiresUnreferencedCode("Evaluates expression-based member chains via reflection; members may be trimmed.")]
public static bool TrySetValueToPropertyChain<TValue>(object? target, IEnumerable<Expression> expressionChain, TValue value)
Summary: Based on a list of expressions, attempts to set the value of the last property in the chain, throwing on missing members.
Type parameters
| Name | Description |
|---|---|
TValue | The type of the end value being set. |
Parameters
| Name | Type | Description |
|---|---|---|
target | object? | The object that starts the property chain. |
expressionChain | IEnumerable | A sequence of expressions that point to properties/fields. |
value | TValue | The value to set on the last property in the chain. |
Returns: bool -- True if the value was successfully set; otherwise false.
Exceptions
| Type | Condition |
|---|---|
| System.InvalidOperationException | Thrown when expressionChain is empty. |
| System.ArgumentNullException | Thrown when target is null and traversal is required. |
| System.ArgumentException | Thrown when a required member is not settable. |
2. Overload¶
Attributes: [RequiresUnreferencedCode("Evaluates expression-based member chains via reflection; members may be trimmed.")]
public static bool TrySetValueToPropertyChain<TValue>(object? target, IEnumerable<Expression> expressionChain, TValue value, bool shouldThrow)
Summary: Based on a list of expressions, attempts to set the value of the last property in the chain.
Type parameters
| Name | Description |
|---|---|
TValue | The type of the end value being set. |
Parameters
| Name | Type | Description |
|---|---|---|
target | object? | The object that starts the property chain. |
expressionChain | IEnumerable | A sequence of expressions that point to properties/fields. |
value | TValue | The value to set on the last property in the chain. |
shouldThrow | bool | If true, throw when reflection members are missing; otherwise fail softly. |
Returns: bool -- True if the value was successfully set; otherwise false.
Remarks
Trimming note: this method may traverse arbitrary member chains represented by expressions; it is not possible
to express a complete trimming contract locally.
Exceptions
| Type | Condition |
|---|---|
| System.InvalidOperationException | Thrown when expressionChain is empty. |
| System.ArgumentNullException | Thrown when target is null and traversal is required. |
| System.ArgumentException | Thrown when shouldThrow is true and a required member is not settable. |
