Class StObj

Namespace
ICSharpCode.Decompiler.IL
Assembly
ICSharpCode.Decompiler.dll

Indirect store (store to ref/pointer). Evaluates to the value that was stored (when using type byte/short: evaluates to the truncated value, sign/zero extended back to I4 based on type.GetSign())

Methods

AcceptVisitor(ILVisitor)

Calls the Visit*-method on the visitor corresponding to the concrete type of this instruction.

public override void AcceptVisitor(ILVisitor visitor)

Parameters

AcceptVisitor<T>(ILVisitor<T>)

Calls the Visit*-method on the visitor corresponding to the concrete type of this instruction.

public override T AcceptVisitor<T>(ILVisitor<T> visitor)

Parameters

visitor ILVisitor<T>

Returns

T

Type Parameters

T

AcceptVisitor<C, T>(ILVisitor<C, T>, C)

Calls the Visit*-method on the visitor corresponding to the concrete type of this instruction.

Parameters

visitor ILVisitor<C, T>
context C

Returns

T

Type Parameters

C
T

CanInlineIntoTargetSlot(ILInstruction)

For a store to a field or array element, C# will only throw NullReferenceException/IndexOfBoundsException after the value-to-be-stored has been computed. This means a LdFlda/LdElema used as target for StObj must have DelayExceptions==true to allow a translation to C# without changing the program semantics. See https://github.com/icsharpcode/ILSpy/issues/2050

public bool CanInlineIntoTargetSlot(ILInstruction inst)

Parameters

inst ILInstruction

Returns

bool
